abstract = {In many real-world applications, data are described by high-dimensional feature spaces, posing new challenges for current ensemble clustering methods. The goal is to combine sets of base clusters to enhance clustering accuracy, but this makes them susceptible to low quality. However, the reliability of present ensemble clustering in high-dimensional data still needs improvement. In this context, we propose a new fuzzy divergence-weighted ensemble clustering based on random projection and spectral learning. Firstly, random projection (RP) is used to create various dimensional data and find membership matrices via fuzzy c-means (FCM). Secondly, fuzzy partitions of random projections are ranked using entropy-based local weighting along with Kullback-Leibler (KL) divergence to detect any uncertainty. Then it used to evaluate the weight of each cluster. Finally, we create regularized graphs from these membership matrices and use spectral matrices to estimate the affinity matrices of these graphs using fuzzy KL divergence anchor graphs. Subsequently, obtaining the final clustering results is considered as an optimization problem, and the ensemble clustering results are obtained. The experimental results on high-dimensional data demonstrate the efficiency of our method compared to state-of-the-art methods.},

abstract = {This paper proposes a new electronic analog circuit to realize real-time fully configurable continuous-time transfer function. The proposed circuit serves various purposes, including smart controllers, fractional-order controllers, optimal controllers, anti-aliasing filter, and programmable filters. The input signal of the transfer function is continuous and remains continuous throughout the circuit until the output signal is obtained. The proposed approach decomposes the transfer function into elementary first and/or second-order low-pass filters. A new analog first-order low-pass filter circuit is presented, offering advantages over conventional active first-order low-pass filters circuits. These benefits include DC gain and time constant independent of resistor ohmic values, enabling the use of smaller resistors and capacitors for low frequencies, and an expanded frequency working range. Similarly, a new analog circuit for a second-order low-pass filter is proposed, specifically used to obtain complex conjugate poles. The use of digital potentiometers and digital switches controlled by a micro-controller, makes this analog circuit configurable in real-time. As an application, the new circuit is used to realize fractional integrator controller. The circuit gives good similarity between theoretical and experimental measurements. © 2024 Elsevier GmbH},

To estimate the sensors faults descriptor approach is investigated. This method consists in augmenting the state system by considering the fault as an auxiliary state. The used observer can simultaneously estimate both the state system and sensors faults. The observer gains are then determined according to Linear Matrix Inequalities (LMI) technique. For fault tolerant control we present two control strategies which stabilize the system not only in free-fault case, but also in the fault occurrence. The first one consists in determine the state-feedback gain and the second one is based on the static output-feedback control. A numerical example is proposed to demonstrate the effectiveness and the merit of the given design.},

Nonlinear and uncertain systems are common in many industrial applications, and achieving effective control for them is a major engineering challenge.The Backstepping method, a control technique based on recursion, is first introduced to stabilize nonlinear and uncertain dynamic systems. It allows for the design of successive control laws by progressively moving up the chain of the system’s state variables, stabilizing them one by one. This approach offers significant flexibility in handling a variety of nonlinear and uncertain systems.Next, Adaptive Backstepping is presented as an extension of the basic method. This approach takes into account uncertainties and parametric variations in the system, making it particularly well-suited for systems whose characteristics may change over time. Adaptive Backstepping automatically adjusts control laws to maintain system stability and performance, even in the presence of unknown disturbances and uncertainties.},

abstract = {In recent years, researchers have focused on improving the efficiency of photovoltaic systems, as they have an extremely low efficiency compared to fossil fuels. An obvious issue associated with photovoltaic systems (PVS) is the interruption of power generation caused by changes in solar radiation and temperature. As a means of improving the energy efficiency performance of such a system, it is necessary to predict the meteorological conditions that affect PV modules. As part of the proposed research, artificial neural networks (ANNs) will be used for the purpose of predicting the PV system’s current and voltage by predicting the PV system’s operating temperature and radiation, as well as using JAYA-SMC hybrid control in the search for the MPP and duty cycle single-ended primary-inductor converter (SEPIC) that supplies a DC motor. Data sets of size 60538 were used to predict temperature and solar radiation. The data set had been collected from the Department of Systems Engineering and Automation at the Vitoria School of Engineering of the University of the Basque Country. Analyses and numerical simulations showed that the technique was highly effective. In combination with JAYA-SMC hybrid control, the proposed method enabled an accurate estimation of maximum power and robustness with reasonable generality and accuracy (regression (R) = 0.971, mean squared error (MSE) = 0.003). Consequently, this study provides support for energy monitoring and control. © 2023 by the authors.},

The proposed idea is to use Higher-Order Statistics (HOS), such as fourth-order cumulants (foc), instead of noisy input and output measurements to obtain unbiased estimates. Firstly, all differentiation orders are assumed to be known a priori and linear coefficients are estimated. The developed estimator is based on minimizing the equation error and it is called fractional fourth-order based-least squares estimator (frac- foc- ls). Secondly, the global commensurability of the fractional MISO system is considered. The frac- foc- ls is combined with a non linear technique to estimate the global commensurate order along with linear coefficients. The developed algorithm is based on minimizing the output error and called fractional fourth-order cumulants based-least squares combined with global commensurate order optimization (frac- foc- gcools). The consistency of the developed estimators, in presence of high levels of noise corrupting both the input and output measurements, is assessed through a numerical example with the help of Monte Carlo simulations. © 2023, Diogenes Co.Ltd.},

abstract = {A fractional-order controller is an infinite-memory system. It is described by a continuous time irrational transfer function. Its realization is a delicate problem especially when its parameters are real time tunable. This paper presents a real-time programmable analogue fractional controller implementation. The controller is based on a sum of a novel real-time programmable analogue first-order low-pass filter. The signal within the circuit remains analogue and is not converted into discrete values. Real-time adjustments are made using digital potentiometers and operational amplifiers. The proposed first-order low-pass filter offers several advantages. In particular, the time constant and DC gain are independently adjusted without relying on the ohmic value of digital potentiometers. The time constant and DC gain depend on the resolution of the digital potentiometers. The high resolution of the digital potentiometer enables the circuit to achieve a wide bandwidth and allows for the use of small capacitors at lower frequencies. The proposed real-time programmable analogue fractional controller is experimented to achieve a fractional integrator. The circuit yields good similarity between theoretical simulations and experimental measurements. © 2023 IEEE.},

abstract = {In this paper we propose a new optimization technique based on an evolutionary method known as particle swarm optimization (PSO) for solving and specifying the switching instants of hybrid systems. The main objective is to minimize a performance measure that depends on these switching instants within a finite time interval. Our approach assumes that there is a predefined sequence of system modes and, at each switching instant, it is possible for a state-space variable to jump from one mode to another, resulting in an additional associated cost. Our approach is justified by numerical examples and compared with the results obtained by gradient-based methods. The results obtained by PSO are very promising, without requiring any a priori assumptions about the regularity of the objective function to be minimized. © 2023 IEEE.},

abstract = {Typically, the process of determining dynamic parameters for robots entails the utilization of the Inverse Dynamic Model (IDM), which exhibits linearity concerning the parameters under identification. This is coupled with the application of Linear Least Squares (LLS) techniques. To execute this method, it is imperative to acquire highly accurate measurements of both torque and position at a high sampling frequency. Moreover, it is necessary to estimate velocities and accelerations by applying a band-pass filtering method to the positional data. Because of the presence of noise within the observation matrix and the iterative nature of the identification process, we have adapted the Instrumental Variable (IV) method to tackle the challenge of noisy observations. A recent successful application involved a novel identification approach called the Direct and Inverse Dynamic Identification Model (DIDIM), which relies solely on torque measurements as its input variables. The experimental findings demonstrate that the IV and DIDIM techniques yield comparable numerical results. In this paper, we undertake a comparative analysis of these two approaches using a double step least squares (2SLS) examination. To substantiate our findings, we carry out experimental validation using a 2-degree-of-freedom planar robot. © 2023 IEEE.},

abstract = {Skin lesions classification is a crucial endeavor in dermatology, as precise diagnosis is critical for improving patient outcomes and lowering the incidence of skin cancer. The PAD-UFES-20 dataset is very relevant for this task since it contains 2,298 imbalanced skin lesions smartphone images. Thus, data sampling techniques such as Random Over Sampling (ROS) and SMOTE were applied to overcome this issue. This work is based on two scenarios. The first scenario aims to classify the whole six classes figuring in this dataset, using various powerful proposed methods based on Deep Learning (DL) models. The best performance was achieved when employing EfficientNetB0 with data ROS, as it reached an accuracy of 92.01%, F1-score of 92.01%, and AUC of 97.12%. The objective of the second scenario is to make a triage between two skin lesions: Melanoma and Nevus using DL techniques. The results of the use of an EfiicientNetB1 with data ROS demonstrated a high level of accuracy, F1-score, and AUC, with a measurement of 98.98%, 99.22%, and 99.95%, respectively. The study's high-performance shows that these methods might have the potential to be a useful tool for clinicians in the examination and diagnosis of skin lesions, thereby enhancing the healthcare quality. © 2023 IEEE.},

abstract = {Internet's lightning-fast growth and the smartphone industry has led to the emergence of the Internet of Things (IoT), which aims to connect all objects/devices to the Internet so that automated objects can interact with their environment and communicate data eliminating the need for human interaction. IoT has the potential to transform industries and enable new forms of innovation and efficiency, but it also poses challenges in terms of privacy, security, and data management. As the number of connected devices continues to grow, it will be essential to develop standards and best practices to assure IoT system reliability and safety. To accomplish these obstacles of efficient data sharing and authorized access control, otherwise decentralized automation, security, and stakeholder trust management in the IoT, a new technology called Blockchain has emerged. In this context, this paper introduces Blockchain technology, which is characterized by decentralization, transparency, and immutability. It can be used to solve some of the challenges facing IoT systems, such as data security and confidentiality.

As a key part of Industry 4.0, IoT has been widely used in various industrial fields. The integration of Blockchain and IoT technologies in Industry 4.0 plays an important role in improving the performance of systems in Industry. This integration improves classic deterministic interactions between industrial devices to become intelligent interactions. Blockchain is an advanced technology that leads to robust distributed applications. It is a tamperproof, decentralized, immutable and transparent database. In this paper, we present the principle of monetization as a principle of interaction between industrial objects.

abstract = {The area of medical imaging has experienced a remarkable expansion in recent times, with radiologists heavily depending on medical images for precise diagnoses. However, radiologists often encounter difficulties when presented with cases of uncertain diagnoses as they struggle to find comparable cases in both public and internal databases to assist them in their decision-making. This manual search process not only detracts from the ability to diagnose new cases but also places a considerable burden on radiologists' workflow. To tackle these challenges, this study suggests a computer-aided system that can automatically retrieve annotated medical images with similar content. This system incorporates a feature extractor based on deep learning, designed to simplify the process of identifying comparable images from an extensive chest radiograph database. The main focus of this study is on the feature extractor, which utilizes YOLOv5 and EfficientNet. YOLOv5 is known for its fast and efficient object detection framework, while the EfficientNet-B0 encoder block serves as an image retrieval and EfficientNet-B3 helps prevent noisy predictions. The study conducted experiments on a large dataset to evaluate the performance of the proposed solution. The results demonstrate that the model outperforms other classical approaches, with a mean average precision of 0.488 at a threshold of 0.9, which is higher than the performance of YOLOv5+ResNet, and EfficientDet of 0.234 and 0.257 respectively. Moreover, the model precision was significantly higher, with a precision of 0.864 for all pathologies, which was 0.352 higher than YOLOv5+ResNet and EfficientDet. Overall, the proposed computer-assisted system has the potential to enhance the efficiency of radiologists' workflow by offering a more effective and efficient tool for retrieving similar annotated medical images. This study is a significant advancement in the development of intelligent and efficient image retrieval systems in the medical imaging field. The proposed solution has the potential to significantly impact the diagnosis of complex medical cases, particularly in emergency departments. © 2023 IEEE.},

abstract = {One of the most expensive and fatal natural disasters in the world is forest fires. For this reason, early discovery of forest fires helps minimize mortality and harm to ecosystems and forest life. The present research enriches the body of knowledge by evaluating the effectiveness of an efficient wildfire and smoke detection solution implementing ensembles of multiple convolutional neural network architectures tackling two different computer vision tasks in a stage format. The proposed architecture combines the YOLO architecture with two weights with a voting ensemble CNN architecture. The pipeline works in two stages. If the CNN detects the existence of abnormality in the frame, then the YOLO architecture localizes the smoke or fire. The addressed tasks are classification and detection in the presented method. The obtained model’s weights achieve very decent results during training and testing. The classification model achieves a 0.95 F1-score, 0.99 accuracy, and 0.98e sensitivity. The model uses a transfer learning strategy for the classification task. The evaluation of the detector model reveals strong results by achieving a 0.85 mean average precision with 0.5 threshold (mAP@0.5) score for the smoke detection model and 0.76 mAP for the combined model. The smoke detection model also achieves a 0.93 F1-score. Overall, the presented deep learning pipeline shows some important experimental results with potential implementation capabilities despite some issues encountered during training, such as the lack of good-quality real-world unmanned aerial vehicle (UAV)-captured fire and smoke images. © 2023 by the authors.},

abstract = {Multiple Sclerosis (MS) lesions is a chronic autoimmune inflammatory disease that affects the nerves in the spinal cord and the brain. Magnetic Resonance Imaging (MRI) is a successful, highly sensitive MS lesion diagnostic technique. It is used to monitor the activity and progression of this disease. Monitoring the progression of multiple sclerosis (MS) is crucial for timely intervention and treatment adjustments, as it can help improve patients' quality of life and contribute to ongoing research efforts to better understand the disease. This paper uses two techniques to monitor MS lesions progression: the Decimal Descriptor Pattern (DDP) and the Local Binary Pattern (LBP). These operators are used to extract the most important features and to characterize the properties of the structures in the brain. 3D MRI brain are described using a collection of orthogonal planes. We have developed an extension to the DDP descriptor to improve the performance in MS evolution. Our results are proof that our approach is effective and fast. © 2023 IEEE.},

abstract = {In recent years, researchers have focused on improving the efficiency of photovoltaic systems, as they have an extremely low efficiency compared to fossil fuels. An obvious issue associated with photovoltaic systems (PVS) is the interruption of power generation caused by changes in solar radiation and temperature. As a means of improving the energy efficiency performance of such a system, it is necessary to predict the meteorological conditions that affect PV modules. As part of the proposed research, artificial neural networks (ANNs) will be used for the purpose of predicting the PV system’s current and voltage by predicting the PV system’s operating temperature and radiation, as well as using JAYA-SMC hybrid control in the search for the MPP and duty cycle single-ended primary-inductor converter (SEPIC) that supplies a DC motor. Data sets of size 60538 were used to predict temperature and solar radiation. The data set had been collected from the Department of Systems Engineering and Automation at the Vitoria School of Engineering of the University of the Basque Country. Analyses and numerical simulations showed that the technique was highly effective. In combination with JAYA-SMC hybrid control, the proposed method enabled an accurate estimation of maximum power and robustness with reasonable generality and accuracy (regression (R) = 0.971, mean squared error (MSE) = 0.003). Consequently, this study provides support for energy monitoring and control. © 2023 by the authors.},

abstract = {This paper presents new consistent methods for continuous-time Multiple-Input-Single-Output (MISO) Errors-In-Variables (EIV) systems by fractional models. The proposed idea is to use Higher-Order Statistics (HOS), such as fourth-order cumulants (foc), instead of noisy input and output measurements to obtain unbiased estimates. Firstly, all differentiation orders are assumed to be known a priori and linear coefficients are estimated. The developed estimator is based on minimizing the equation error and it is called fractional fourth-order based-least squares estimator (frac- foc- ls). Secondly, the global commensurability of the fractional MISO system is considered. The frac- foc- ls is combined with a non linear technique to estimate the global commensurate order along with linear coefficients. The developed algorithm is based on minimizing the output error and called fractional fourth-order cumulants based-least squares combined with global commensurate order optimization (frac- foc- gcools). The consistency of the developed estimators, in presence of high levels of noise corrupting both the input and output measurements, is assessed through a numerical example with the help of Monte Carlo simulations. © 2023, Diogenes Co.Ltd.},

To do so, we design a new structure of interval observers by introducing weighted matrices not only to give more degrees of design freedom but also to attenuate the conservatism caused by uncertainties. Observer gains are derived from the solution of Linear Matrix Inequalities (LMIs), based on the use of a common Lyapunov function, to ensure cooperativity and stability. An L∞ technique is then introduced to compensate the measurement noise and disturbances' effects and to enhance the precision of interval estimation. Finally, numerical simulations are given, evaluating the proposed methodology and demonstrating its effectiveness. © 2023 IEEE.},

Each vehicle wishing to be part of this platoon must send a configuration and registration message and must provide the necessary information to be part of the platoon. This new feature can reduce traffic congestion and save energy. This article, paves the way for the emergence of a new type of driving system that we will call "EX-platoon"extensible platoon abbreviation. Thus, through this document, we will develop a model based on a Petri network describing the flow of messages exchanged between the different parts of this system necessary to allow the cooperative driving system to be extensible.

abstract = {The authors’ work deals with modelling with coloured Petri nets (CPN) of network controlled systems (NCS) and exposes a proposal of a sensor fault detection and prevention mechanism. In NCS, the network must be viewed as part of the system and not just a means of communication. For this, two issues must be considered. The first consists of adapting the control and diagnostic laws to the performance of the network. The second is to guarantee the performance of the system. Each control loop containing a network is vulnerable to faults and cyber attacks and malicious users can intercept and listen to data during transmission. For that reason, it is essential to protect transmitted data against unauthorized access and modification and to diagnose components. In this paper, the authors presented a model with CPN of a NCS, the authors proposed a sensor fault detection and correction mechanism, then the authors injected a sensor fault and the authors tested the effectiveness of the proposed mechanism in detecting that fault and correcting its influence. Simulation results proved the success of the preventive mechanism in overcoming the influence of the fault and returning to normal behaviour. © 2022 The Authors.

Main performance indexes lower latency and power consumption. It's widely known that this is the most reliable choice for the post-fifth physical layer. Mobile networks adopt a famous modulation model named OTFS (Orthogonal Time-Frequency Space). So, the paper concerns how better an equalization procedure will be based on both ZF (zero forcing) and MMSE (minimum mean square error equalization) with respect to offered complexity.

abstract = {A fractional-order controller is an infinite-memory system. It is described by a continuous time irrational transfer function. Its realization is a delicate problem especially when its parameters are real time tunable. This paper presents a real-time programmable analogue fractional controller implementation. The controller is based on a sum of a novel real-time programmable analogue first-order low-pass filter. The signal within the circuit remains analogue and is not converted into discrete values. Real-time adjustments are made using digital potentiometers and operational amplifiers. The proposed first-order low-pass filter offers several advantages. In particular, the time constant and DC gain are independently adjusted without relying on the ohmic value of digital potentiometers. The time constant and DC gain depend on the resolution of the digital potentiometers. The high resolution of the digital potentiometer enables the circuit to achieve a wide bandwidth and allows for the use of small capacitors at lower frequencies. The proposed real-time programmable analogue fractional controller is experimented to achieve a fractional integrator. The circuit yields good similarity between theoretical simulations and experimental measurements. © 2023 IEEE.},

By taking the fault as an auxiliary state vector, the proposed method consists of two steps. First, a switched L∞-based descriptor observer attenuating the effect of uncertainties is designed to obtain simultaneous point estimate of the system state and the fault term. Second, interval estimation is achieved by integrating robust point estimation with zonotopic analysis techniques. The observer gains are calculated by solving Linear Matrix Inequality (LMI) derived using a common Lyapunov function. Finally, the effectiveness of the proposed approach is demonstrated through a numerical example. Copyright © 2023 The Authors.

The SRR design is intended to provide bandstop functionality within the antenna bandwidth. As a result, the mutual coupling level is reduced by 23 dB while maintaining the antenna's performance and by packing the MIMO structure with three cells of SRR. In addition, the prototype antenna's simulated isolation varies from -32 to -55 dB on the frequency band of 25.5-26.6 GHz. The reflection coefficient is roughly -40 dB at 26 GHz, with a high gain of 7.5 dB and efficiency higher than 90%. This makes our antenna an effective competitor for MIMO applications at the 26 GHz band enabling the fifth generation (5G) cellular communications. © 2023 IEEE.},

Nonlinear and uncertain systems are common in many industrial applications, and achieving effective control for them is a major engineering challenge. The Backstepping method, a control technique based on recursion, is first introduced to stabilize nonlinear and uncertain dynamic systems. It allows for the design of successive control laws by progressively moving up the chain of the system's state variables, stabilizing them one by one. This approach offers significant flexibility in handling a variety of nonlinear and uncertain systems. Next, Adaptive Backstepping is presented as an extension of the basic method. This approach takes into account uncertainties and parametric variations in the system, making it particularly well-suited for systems whose characteristics may change over time. Adaptive Backstepping automatically adjusts control laws to maintain system stability and performance, even in the presence of unknown disturbances and uncertainties. © 2023 IEEE.},

However, such systems have different configurations and strategies, each with its own advantages and drawbacks. To design a suitable system, this paper proposes a method that utilizes a single-stage conversion system with hydraulic storage. In this method, the predictive torque controller (PTC) adjusts the inverter switching while the electrical storage in batteries is replaced by the potential energy of water in tanks. The PTC works side-by-side with a maximum power point tracking (MPPT) technique to supply the optimal power to the water-pumping Induction Motor (IM). This maximum power tracking is maintained during the day hours to provide and store water, whereas the water supply is guaranteed due to the gravity at night. The effectiveness of the proposed system is evaluated through MATLAB/Simulink-based results, demonstrating that the single-stage configuration outperforms the double-stage configuration in terms of power optimization, torque ripples, and power loss reduction. Furthermore, the suggested system offers the advantage of cost-effective installation due to its simple structure. © 2023 Taylor \& Francis Group, LLC.},

In this paper, the performance of MMSE based in terms of speckle reduction and spatial detail preservation is revised. To preserve the spatial details, the weight coefficient $b$ should be equal to 1. However, the authors demonstrated in this paper that this parameter do not fulfill this condition. As a consequence, the MMSE-based filters have some limitations in spatial detail preservation. In PolSAR filtering, the weight coefficient $b$ is estimated from the span image. However, it has been demonstrated that the standard deviation of the span (i. e. $sigma_v(span)$) is a pixel dependent. The use of a fixed $sigma_v(span)$ for the entire image as applied in the majority of the state of the art MMSE filters is not optimal.},

abstract = {Speckle filtering is essential for accurate parameter estimation from polarimetric synthetic aperture (PolSAR) data. To reduce speckle, sufficiently large independent samples (i. e. N looks) are generally averaged. However, in real scene, these N-looks are not provided. To surmount this limitation, by exploiting the ergodicity of the SAR data, the multilooking is substituted by the spatial averaging of N homogenous neighboring pixels. In this letter, it has been demonstrated that the multilooking and spatial averaging are quite different. First, the spatial averaging introduced a correlation between the pixels whereas in the multilooking they remain independent. Secondly, in real scene, the spatial averaging estimation of the polarimetric parameters (i.e. intensity mean and variance, equivalent number of looks (ENL), entropy and alpha angle) is nosier and more biased than the multilooked ones. These results should be taken into account when dealing with PolSAR parameter estimation of real data from multilooked PolSAR data models.},

abstract = {This brief studies the problem of state and fault estimation for Non-Linear (NL) systems with time delay subject to sensor fault. Additive fault tolerant control (FTC) is proposed to achieve the stability of system. The original system is transformed to linear one. The principle of fault accommodation is based on adding a new order to this nominal order. When a sensor fault affects the system, the tracking error between the reference input and the measurement deviates from zero. The nominal command then changes in order to cancel the static error and the real output therefore become different from its reference value. In the presence of a sensor defect, the objective of the accommodation is to prevent the command to evolve. This task can be accomplished by analyzing and canceling the effect of the sensor fault on the $mathbfu$ command. After determining the amplitude of the fault, we move on to its compensation step, this step is done by adding the additive control law to the determined nominal control law. The generation of nominal control law consist to determinate the state feedback gain by using the pole placement technique.},

To accomplish fault isolation, we use a bank of observers for all possible faulty models. The paper considers constant actuator faults, that is, the outputs of some actuators are stuck at fixed undesirable constant values. The fault isolation strategy is based on combining the conventional observer design techniques with adaptation techniques. Based on the designed observers, a bank of residuals are defined correspondingly. The actuator faults can be isolated if only one residual goes to zero while the others do not. The faulty model with residual approaching zero identifies the faulty actuators. For linear and nonlinear systems with all states available, new sufficient conditions for fault isolation are derived, which require only that the distribution matrices of the actuators are of full column rank.},

abstract = {This paper deals with continuous-time system identification of multiple-input single-output (MISO) fractional differentiation models. When differentiation orders are assumed to be known, coefficients are estimated using the simplified refined instrumental variable method for continuous-time fractional models extended to the MISO case. For unknown differentiation orders, a two-stage optimization algorithm is proposed with the developed instrumental variable for coefficient estimation and a gradient-based algorithm for differentiation order estimation. A new definition of structured-commensurability (or S-commensurability) is introduced to better cope with differentiation order estimation. Three variants of the algorithm are then proposed: (i) first, all differentiation orders are set as integer multiples of a global S-commensurate order, (ii) then, the differentiation orders are set as integer multiples of a local S-commensurate orders (one S-commensurate order for each subsystem), (iii) finally, all differentiation orders are estimated by releasing the S-commensurability constraint. The first variant has the smallest number of parameters and is used as a good initial hit for the second variant which in turn is used as a good initial hit for the third variant. Such a progressive increase of the number of parameters allows better performance of the optimization algorithm evaluated by Monte Carlo simulation analysis. © 2022 Elsevier Ltd},

abstract = {The paper deals with passive fault tolerant control for linear parameter varying systems subject to component faults. Under the assumption that the faults magnitudes are considered unknown but bounded, a novel methodology is proposed using interval observer with an (Formula presented.) formalism to attenuate the effects of the uncertainties and to improve the accuracy of the proposed observer. The necessary and sufficient conditions of the control system stability are developed in terms of matrix inequalities constraints using Lyapunov stability theory. Based on a linear state feedback, a fault tolerant control strategy is designed to handle component faults effect as well as external disturbances and preserve the system closed-loop stability for both fault-free and component faulty cases. Two simulation examples are presented to demonstrate the effectiveness of the proposed method. © The Author(s) 2021.},

In this paper, we consider the problem of identifying continuous-time fractional systems from noisy input and output measurements. The bias correction scheme, which aims at eliminating the bias introduced by the fractional order ordinary least squares method, is presented, based on the estimation of variances of the input and output measured noises. The compensation method for the input and output noises is also studied by introducing an augmented high-order fractional-order system in the identification algorithm. The presented algorithm is established to perform unbiased coefficients and fractional orders estimation. The promising performances of the proposed method are assessed via the identification of a fractional model and a fractional real electronic system. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.},

The span is a summation of the three polarimetric intensity channels, its probability density function (pdf) is commonly assumed in the literature as that of the intensity polarimetric channel. In this letter, the statistics of the span are investigated. It has been demonstrated that the span is modeled by $L$ -looks intensity pdf where $L$ is the equivalent number of looks (ENLs) of the span transformation, i.e., ENLspan. To estimate ENLspan, a theoretical model has been proposed. The results showed that ENLspan ranges in [1,3] depending on the media’s scattering property. Results demonstrated also that the use of the eigenvalues produced better estimation of ENLspan than the use of diagonal elements of the coherence or the covariance matrix. The proposed model produced also a more accurate estimation of ENLspan than the one obtained by the direct calculation. Finally, it has been demonstrated that the use of the introduced span statistics gave a correct estimation of the performance of the classification and the filtering PolSAR techniques whereas classical span statistics overestimated them.},

Blockchain technology provides just such a solution in the form of a distributed and secure registry that allows patients not only to have visibility over their data, but also to control access to it.

abstract = {Medical imaging methods identify and record anomalies inside the human body; these techniques are critical for assessing, diagnosing, and treating chest infections and diseases; the thoracic radiography known by chest X-ray is a non-expensive, yet very effective, medical imaging technique. However, a scarcity of competent radiologists might significantly limit the technique's usefulness. To increase performance and diagnosis accuracy, new technologies such as deep learning must be used to detect aberrant chest X-ray. Recently, machine-learning algorithms based on convolutional layers have made a significant progress. The success of convolutional neural network (CNN) in image classification has led researchers to investigate its usefulness as a diagnosis method for identifying and characterizing pulmonary diseases. We propose to use the modified MobileNet V2 model to classify and predict lung lesions in frontal chest X-rays.

A Kalman filter approach is proposed for state prediction and intermittent unknown input reconstruction. The filter design is based on the minimization of the trace of the state estimation error covariance matrix under the constraint that the state prediction error is decoupled from active unknown inputs corrupting measurements at the current time. When the system is not strongly detectable, a sufficient stochastic stability condition on the mathematical expectation of the random state prediction errors covariance matrix is established in the case where the arrival binary sequences of unknown inputs follow independent random Bernoulli processes. When the intermittent unknown inputs on measurements represent intermittent observations, an illustrative example shows that the proposed filter corresponds to a Kalman filter with intermittent observations having the ability to generate a minimum variance unbiased prediction of measurement losses. © 2022 Taouba Rhouma et al., published by Sciendo.},

It enables information to be stored and exchanged securely and transparently without the need for a centralized authority to regulate it. A few of the primary benefits of this technology is the atomicity of the stored data. Given its features, this technology has the potential to give answers to challenges encountered in a very sensitive sector, notably healthcare. The medical field is dealing with several issues that some are attempting to address today. The most important are the administration of medical records and the claims process, the acceleration of clinical and biomedical research, and the advancement of the biomedical and health data registry. The major challenge is the processing and analysis of patient records due to the large amount of data collected. The security of this data is another challenge to consider. Due to the high connectivity, these systems are prone to malicious attacks. In addition, it is difficult to ensure confidentiality due to the exchange of sensitive data.

abstract = {Computer vision has made a significant advance in the medical imaging. Pneumothorax is a severe ailment that can be fatal if the patient does not receive proper care. The main way for diagnosing Pneumothorax is by examining the Chest X-ray by a specialist. The urge of experienced radiologists to anticipate whether someone is suffering from pneumothorax or not by examining chest X-rays is indisputable. Such a facility is not available to everyone. Furthermore, in some circumstances, quick diagnosis is required. In this paper We present a deep learning based image segmentation model capable of predicting Pneumothorax cases by localizing it in chest x-ray exam to help the doctor in making this critical choice. Deep Learning has demonstrated its value in multiple domains, outperforming several state-of-the-arts methods. We seek to overcome this challenge by leveraging deep learning capabilities. We used U-Net architecture with Xception as the encoder and ResNet as a decoder. We obtained encouraging findings, and U-Net works exceptionally well in medical imaging. Our work is listed with in as semantic segmentation. With 77.8 (±0.15), our technique obtains a good outcome in terms of Intersection over Union. © 2022 IEEE.},

abstract = {The Energy saving in wireless sensor network has become one of the ascending issue. To manage the remaining energy in nodes and extend the life time of the network, clustering is one of the efficient solution. Structuring homogenous and stable clusters as well as choosing the optimal cluster head is the key of an energy efficient clustering. This paper deals with an Energy Aware Cluster head selection protocol based on balanced Fuzzy c-mean clustering approach. This approach proposes uniform and stable cluster formation using Balanced Fuzzy c-mean algorithm with modified centroid. As for Cluster Head selection, three parameters are considered such as Residual energy of the node, Distance from the Base Station and Distance-Ratio. Simulation results on Matlab of the proposed approach are compared to basic energy efficient approaches such as LEACH, C-LEACH and TSI-LEACH. © 2022 IEEE.},

abstract = {Despite the rapid development of the Internet of Things technologies where more and more medical sensors and gadgets are connected to the Internet, limited energy resources due to transmission, and security are still main challenges. Most cases, patients wear multiple medical devices that transmit sensed medical data wirelessly to servers, which might cause big traffic on the communication networks, which in turn cause high energy consumption. Therefore, using the data aggregation, we can considerably reduce the energy consumption by eliminating redundant data; yet collected data must be fully protected. Secure data collection and transfer to centralized servers in healthcare applications employing IoT is quite challenging to protect against several attacks for illegal data access. For this reason, massive security measures should be taken to ensure that patients’ data can only be accessed by legitimate users. This paper proposes EPPADA: Efficient Privacy‑Preserving Authentication and Data Aggregation scheme in conjunction with Homomorphic Encryption concepts to meet requirements of healthcare using IoT with green computing technologies. The main objective of this proposed scheme is to decrease the communication overhead and energy consumption while maintaining safe and secure aggregation of the healthcare data between medical sensors and cloud servers. The proposed system is experimentally developed using E-health sensor shield V2.0 platform. Based on security analysis that has the most extensive set of security features, our multi-objective approach enhances the End-to-End Delay, Computational Cost, Communication Overhead, besides maintaining security features. © 2022},

abstract = {In the recent past the Internet of Things (IoT) is moving from interactive objects to smart objects. The number of smart devices or sensors built-in becomes larger. The increase in the number of services exchanged between connected objects has led to the creation of a new concept called Social IoT (SIoT), in which heterogeneous or homogeneous objects can interact and request or exchange services, which makes it possible to include social or human actions in the IoT platform. The use of technologies based on the concept of the Internet of Things in applications and industrial sectors has built a new concept of research called the Industrial Internet of Things (IIoT). The integration of the SIoT concept into the Industrial Internet of Things (IIoT) plays an important role in improving system performance in Industry 4.0 and gives rise to the Social Internet of Industrial Things (SIoIT). In this context, we have revealed a new socio-inspired interaction model between industrial communicating objects inspired by sociological approaches that transform objects into socialized industrial communicating objects. These objects form a community, autonomously and dynamically, by exchanging messages to know each other perfectly, and service requests between objects are realized in an adaptive way according to the principles of social interaction governed by socio-inspired strategies and conditions. The model is evaluated using Netlogo multi-agent system simulation environment. Copyright © 2022 The Authors. This is an open access article under the CC BY-NC-ND license.},

Thus, this contribution implements a technique based on the bias compensation principle.

abstract = {The wireless sensor network (WSN) is used to monitor environmental or phenomena physical, such as noise, pressure, motion or temperature, and to transmit data to the capital. Nowadays, with the explosive growth of IoT technology, more and more practical applications can be found in many fields, including security, smart metering, agriculture, smart cities and more domestic intelligence. There are other applications, especially military, home automation, industrial, sanitary, and especially medical applications and sanitary. This article suggests and explores home health care. The Arduino can be used to perform a portable ECG with the heart condition reading function. The main component of this system is the AD8232 sensor which can read the heart rate and process the voltage of the electrodes connected to the body. By combining the Arduino UNO microprocessor and HC 05 FC-114 as Bluetooth or Wifi, ZigBee antenna, GSM/GPRS and even XBee, the ECG screen is displayed in real time on a smartphone. We used an ECG simulator as an artificial corrective agent which is used as a tool to justify the performance of a portable ECG supported on the results obtained from the test. The EGC can be sent via the simulator to the smartphone or to the Matlab interface through a wireless communication module (ZigBee, Bluetooth, Wifi, GSM / GPRS or XBee). The exact result shows the patient's condition in real time. In this article, ECG results are published through the Matlab interface. © 2022 IEEE.},

abstract = {In the present paper, the design problem of fault tolerant control for neutral time delay systems with delayed inputs is studied. The proposed control law is composed into two terms, a nominal control and an additive control. The first term presents the designed state feedback proposed to develop a control strategy which maintains the stability and the desired performance in closed loop system, even in presence of faults. In this case, the Linear Matrix Inequality (LMI) resolution method is applied to determine the feedback gain of the controller. The second one is based on adding an additive fault corrective term to the nominal law. Therefore, the use of unknown inputs observers (UIO) presents an efficient solution for the fault detection and estimation. Finally, the effectiveness of the proposed strategy is proven through a numerical example by the application of the theoretical results to a neutral time delay system with delayed inputs. © 2022 IEEE.},

abstract = {This paper deals with continuous-time system identification of multiple-input single-output (MISO) fractional differentiation models. When differentiation orders are assumed to be known, coefficients are estimated using the simplified refined instrumental variable method for continuous-time fractional models extended to the MISO case. For unknown differentiation orders, a two-stage optimization algorithm is proposed with the developed instrumental variable for coefficient estimation and a gradient-based algorithm for differentiation order estimation. A new definition of structured-commensurability (or S-commensurability) is introduced to better cope with differentiation order estimation. Three variants of the algorithm are then proposed: (i) first, all differentiation orders are set as integer multiples of a global S-commensurate order, (ii) then, the differentiation orders are set as integer multiples of a local S-commensurate orders (one S-commensurate order for each subsystem), (iii) finally, all differentiation orders are estimated by releasing the S-commensurability constraint. The first variant has the smallest number of parameters and is used as a good initial hit for the second variant which in turn is used as a good initial hit for the third variant. Such a progressive increase of the number of parameters allows better performance of the optimization algorithm evaluated by Monte Carlo simulation analysis. © 2022 Elsevier Ltd},

abstract = {In this study, a multiscale monitoring method for nonlinear processes was developed. We introduced a machine learning tool for fault detection and isolation based on the kernel principal component analysis (PCA) and discrete wavelet transform. The principle of our proposal involved decomposing multivariate data into wavelet coefficients by employing the discrete wavelet transform. Then, the kernel PCA was applied on every matrix of coefficients to detect defects. Only those scales that manifest overruns of the squared prediction errors in control limits were considered in the data reconstruction phase. Thus, the kernel PCA was approached on the reconstructed matrix for detecting defects and isolation. This approach exploits the kernel PCA performance for nonlinear process monitoring in combination with multiscale analysis when processing time-frequency scales. The proposed method was validated on a photovoltaic system related to a complex industrial process. A data matrix was determined from the variables that characterize this process corresponding to motor current, angular speed, convertor output voltage, and power voltage system output. We tested the developed methodology on 1000 observations of photovoltaic variables. A comparison with monitoring methods based on neural PCA was established, proving the efficiency of the developed methodology. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.},

abstract = {Chemical processes use to be non-minimum phase systems. Thereby, they are a challenge for control applications. In this paper, fuzzy state feedback is applied in the Van de Vusse reaction that has an inverse response. The control design has an integrator to enhance the control performance by eliminating the steady-state error when a step reference is applied. An anti-windup action is used to reduce the undershoot in the system response. In practice, it is not possible to have always access to all the state variables. Thus, a fuzzy state observer is implemented via LMIs. Frequently, the papers that show similar applications present some comments about disturbance rejection. To eliminate the steady-state error when a ramp reference is used, in this work, a second integrator is aggregated. Now, the anti-windup also reduces the overshoot generated due to the usage of two integrators in the final application. Copyright © 2022. The Author(s).

The fault isolation strategy is based on combining the conventional observer design techniques with adaptation techniques. Based on the designed observers, a bank of residuals are defined correspondingly. The actuator faults can be isolated if only one residual goes to zero while the others do not. The faulty model with residual approaching zero identifies the faulty actuators.

abstract = {This brief studies the problem of state and fault estimation for Non-Linear (NL) systems with time delay subject to sensor fault. Additive fault tolerant control (FTC) is proposed to achieve the stability of system. The original system is transformed to linear one. The principle of fault accommodation is based on adding a new order to this nominal order. When a sensor fault affects the system, the tracking error between the reference input and the measurement deviates from zero. The nominal command then changes in order to cancel the static error and the real output therefore become different from its reference value. In the presence of a sensor defect, the objective of the accommodation is to prevent the command to evolve. This task can be accomplished by analyzing and canceling the effect of the sensor fault on the mathbfu command. After determining the amplitude of the fault, we move on to its compensation step, this step is done by adding the additive control law to the determined nominal control law. The generation of nominal control law consist to determinate the state feedback gain by using the pole placement technique. © 2022 IEEE.},

abstract = {In the coming years, major transportation sectors will be electrified, in which more accessible and easy solutions for charging Electric Vehicles (EVs) become vital. Wireless charging is considered one of the best and easiest methods to charge EVs anywhere, even during the driving of cars. To get accurate charging power rates while charging wirelessly, advanced mathematical models are needed to accurately present the charging power. Such models must take into consideration all the coils parameters, shapes, the used compensation topology, and if the system is static or dynamic. This paper presents a comprehensive analysis of the wireless charging systems adapted for EVs by stating the most common charging topologies, and architectures, and by concentrating on the corresponding mathematical models used to calculate the given electrical power as a function of the EV's situation on streets and its speed. Then, it is possible to evaluate the EV autonomy, and an accurate approximation can be determined when EV is on a wireless charging road.

In this letter, the statistics of the span are investigated. It has been demonstrated that the span is modeled by $L$ -looks intensity pdf where $L$ is the equivalent number of looks (ENLs) of the span transformation, i.e., ENLspan. To estimate ENLspan, a theoretical model has been proposed. The results showed that ENLspan ranges in [1,3] depending on the media's scattering property. Results demonstrated also that the use of the eigenvalues produced better estimation of ENLspan than the use of diagonal elements of the coherence or the covariance matrix. The proposed model produced also a more accurate estimation of ENLspan than the one obtained by the direct calculation. Finally, it has been demonstrated that the use of the introduced span statistics gave a correct estimation of the performance of the classification and the filtering PolSAR techniques whereas classical span statistics overestimated them. © 2004-2012 IEEE.},

Trying to imitate a natural human limb, the prosthesis design challenges rehabilitating amputees to resume normal activities. A dynamic model of an ankle-knee active prosthesis is developed without ground reaction in a first case and introduces ground effect in a second one to ameliorate prothesis performances. The obtained models are used to synthesize a control strategy based on TS fuzzy concepts and PID control to reproduce human lower limb behavior in a normal gait and climb and descent of stairs. The RSME errors are calculated to evaluate and compare the various results performances and eventually show the capacity of the proposed control with ground reaction impact on trajectory tracking. The RMSE values obtained for the four outputs of the fuzzy controller are very small for the different modes of locomotion. Moreover, they become weaker when the ground reaction forces are added to the model to show the role of these forces for the body equilibrium maintaining during the gait cycle. The developed approach ensured good trajectories tracking compared to a healthy leg even in presence of disturbances.},

abstract = {This paper deals with system identification for continuous-time multiple-input single-output (MISO) fractional differentiation models. An output error optimization algorithm is proposed for estimating all parameters, namely the coefficients and the differentiation orders. Given the high number of parameters to be estimated, the output error method can converge to a local minimum. Therefore, an initialization procedure is proposed to help the convergence to the optimum by using three variants of the algorithm. Moreover, a new definition of structured-commensurability (or S-commensurability) has been introduced to cope with the differentiation order estimation. First, a global S-commensurate order is estimated for all subsystems. Then, local S-commensurate orders are estimated (one for each subsystem). Finally the S-commensurability constraint being released, all differentiation orders are further adjusted. Estimating a global S-commensurate order greatly reduces the number of parameters and helps initializing the second variant, where local S-commensurate orders are estimated which, in turn, are used as a good initial hit for the last variant. It is known that such an initialization procedure progressively increases the number of parameters and provides good efficiency of the optimization algorithm. Monte Carlo simulation analysis are provided to evaluate the performances of this algorithm. © 2021 Diogenes Co., Sofia.},

A supervised classification framework preceded by mean-shift segmentation is applied using the texture features alone and combined with the normalized difference vegetation index (NDVI). As the segmentation is a crucial step to obtain a good mapping, considerations are given to select the optimal combination of mean-shift input parameters, such as spatial radius and range radius.

abstract = {Waterleakage detection and localization in distribution networks pipelines is a challenge for utility companies. For this purpose, thermal Infrared Radiation (IR) techniques have been widely applied in the literature. However, the classical analysis of IR images has not been robust in detecting and locating leakage, due to presence of thermal anomalies such as shadows. In this study, to improve the detection and location accuracy, a digital image processing tool based on multitemporal IR is proposed. In multitemporal IR analysis, the variation of soil's temperature due to field temperature can be obtained; and hence; estimating variations due to water leakage would be more accurate. An experimental setup was built to evaluate the proposed multitemporal IR water leak detection method. In order to consider the temporal temperature variation due to water leakage and mitigate the field temperature effects, a luminance transformation of the IRimages was introduced. To determine the temporal temperature variation of the soil's surface due to the leakage, several metrics have been considered such as the difference, the ratio, the log-ratio and the coefficient variation (CV) images. Based on the experimental results, the log-ratio and the CVimages were the most robust metrics. Then, based on log-ratio or the CV image, a temporal variation image (TVI) that traduces the temporal IR luminance variation was introduced. The analysis of the TVI image showed that the CV image is less noisy than the log-ratio image, and can more accurately locate the leakage. Finally, based on TVI histogram, a threshold was defined to classify the TVI image into leakage/non-leakage areas. Results showed that the proposed method is capable of accurately detecting and locating water leakage, which is an improvement to the false detections of spatial thermal IR analysis.},

The minimum mean square error estimate of the filtered pixels conducted to the definition of a linear rule between the values of the filtered pixels and their variances. Hence, the filtered pixel for infinite number of looks (INL) is predicted by a linear regression of means and variances for various window sizes. In this article, the infinite number of looks prediction (INLP) filter is explored in details to emphasize its ability to reduce speckle and preserve the spatial details. Then, the linear regression rule has been adapted to PolSAR context in order to preserve the polarimetric information. The number of the processed pixels used in the linear regression is adjusted to the variability of the scene. This effort increased the filtering performances. The reduction of the correlation between the pixels which constitutes an additional filtering criterion is discussed. Compared to the initially applied filter, the results showed that the improved INLP filter increased in speckle reduction level, augmented the preservation of the spatial details, increased the spatial resolution, reduced the correlation between the pixels and better preserved the polarimetric information. Simulated, one-look and multilook real PolSAR data were used for validation.},

This new strategy improves the performances of existing methods and ensures better convergence conditions. Sliding window approach involves previous estimated states and measurements in the observer and the control law structures which increase the number of decision variables in the constraint to be solved and offers less restrictive Linear Matrix Inequality (LMI) conditions. The established sufficient stability conditions are in the form of Bilinear Matrix Inequality (BMI) which is solved in two steps. First, by using a slack variable technique and an appropriate reformulation of the Young’s inequality. Second, by introducing a useful approach to transform the obtained constraint to a more suitable one easily tractable by standard software algorithms. A comparison with the standard case is provided to show the superiority of the proposed H∞ observer-based controller which offers greater degree of freedom.

abstract = {Healthcare is one of the most promising domains for the application of Internet of Things-(IoT-) based technologies, where patients can use wearable or implanted medical sensors to measure medical parameters anywhere and anytime. The information collected by IoT devices can then be sent to the health care professionals, and physicians allow having a real-time access to patients' data. However, besides limited batteries lifetime and computational power, there is spatio-temporal correlation, where unnecessary transmission of these redundant data has a significant impact on reducing energy consumption and reducing battery lifetime. Thus, this paper aims to propose a routing protocol to enhance energy-efficiency, which in turn prolongs the sensor lifetime. The proposed work is based on Energy Efficient Routing Protocol using Dual Prediction Model (EERP-DPM) for Healthcare using IoT, where Dual-Prediction Mechanism is used to reduce data transmission between sensor nodes and medical server if predictions match the readings or if the data are considered critical if it goes beyond the upper/lower limits of defined thresholds. The proposed system was developed and tested using MATLAB software and a hardware platform called "MySignals HW V2."Both simulation and experimental results confirm that the proposed EERP-DPM protocol has been observed to be extremely successful compared to other existing routing protocols not only in terms of energy consumption and network lifetime but also in terms of guaranteeing reliability, throughput, and end-to-end delay. © 2021 Faris A.

Then, we studied the application of metamaterials to the design of MIMO antennas for miniaturization and the performance of antennas, in order to guarantee the proper functioning of the MIMO system with a much reduced separation distance between the radiating elements (λ/12), where the coupling can be very weak. The application of these circular double ring SRRs materials on the front plan of the antenna has contributed to the increasing of the antenna performance is studied in terms of S-Parameters, efficiency, diversity gain (DG), radiation properties and envelop correlation coefficient (ECC). It offers advantages such as the reduction of weight and congestion that is beneficial for their integration into satellite communications systems. © 2021 Institute of Advanced Engineering and Science.

abstract = {This paper deals with system identification for continuous-time multiple-input single-output (MISO) fractional differentiation models. An output error optimization algorithm is proposed for estimating all parameters, namely the coefficients and the differentiation orders. Given the high number of parameters to be estimated, the output error method can converge to a local minimum. Therefore, an initialization procedure is proposed to help the convergence to the optimum by using three variants of the algorithm. Moreover, a new definition of structured-commensurability (or S-commensurability) has been introduced to cope with the differentiation order estimation. First, a global S-commensurate order is estimated for all subsystems. Then, local S-commensurate orders are estimated (one for each subsystem). Finally the S-commensurability constraint being released, all differentiation orders are further adjusted. Estimating a global S-commensurate order greatly reduces the number of parameters and helps initializing the second variant, where local S-commensurate orders are estimated which, in turn, are used as a good initial hit for the last variant. It is known that such an initialization procedure progressively increases the number of parameters and provides good efficiency of the optimization algorithm. Monte Carlo simulation analysis are provided to evaluate the performances of this algorithm. © 2021 Diogenes Co., Sofia.},

To further improve the spatial information description derived by CLBP, which is successfully used in face recognition, we applied the multi-scale completed local binary pattern (MSCLBP) to classify the single-dated image. A supervised classification framework preceded by mean-shift segmentation is applied using the texture features alone and combined with the normalized difference vegetation index (NDVI). As the segmentation is a crucial step to obtain a good mapping, considerations are given to select the optimal combination of mean-shift input parameters, such as spatial radius and range radius. The results of this study indicate that MSCLBP outperforms the single-scale CLBP and the gray-level co-occurrence matrix (GLCM) descriptors in the task of expressing the classes of interests. © 2021, Indian Society of Remote Sensing.},

abstract = {Thoracic radiography (chest X‐ray) is an inexpensive but effective and widely used medical imaging procedure. However, a lack of qualified radiologists severely limits the applicability of the technique. Even current Deep Learning‐based approaches often require strong supervision, e.g., annotated bounding boxes, to train such systems, which is impossible to harvest on a large scale. In this work, we proposed the classification and prediction of lung pathologies of frontal thoracic X‐ rays using a modified model MobileNet V2. We considered using transfer learning with metadata leverage. We used the NIH Chest‐Xray‐14 database, and we did a comparison of performance of our approach to other state‐of‐the‐art methods for pathology classification. The main comparison was by Area under the Receiver Operating Characteristic Curve (AUC) statistics and analyzed the differences between classifiers. Overall, we notice a considerable spread in the achieved result with an average AUC of 0.811 and an accuracy above 90%. We conclude that resampling the dataset gives a huge improvement to the model performance. In this work, we intended to create a model that is capable of being trained, and modified devices with low computing power because they can be implemented into smaller IoT devices. © 2021 by the authors.

abstract = {The emergence of new IoT applications in regional and remote areas has increased the need for a global IoT connectivity beyond existing terrestrial network coverage. However, in many cases, it is not economically viable to build a dedicated terrestrial network to cover these remote areas due to population sparsity and the lack of business case. In this paper, we propose a framework for designing a solar rectenna for IoT-over-satellite applications using nanosatellites. Utilizing such a framework will allow valuable radio spectrum resources to be shared between satellite and terrestrial users. Thus, the autonomous power supply of these objects becomes a big challenge. Indeed, the harvest of solar energy and the conversion of RF energy into electric voltage are a hot topic. Our contribution consists in offering a solar rectenna system to collect solar and RF energy as well as the radio frequency transmission. A parametric study is carried out to follow the influence on the performance of this system. A topology of rectifying circuits is proposed in the present work.

The single and MIMO antennas are simulated and analyzed then fabricated and measured. A good agreement between measurements and simulations is obtained. These configurations, dedicated to covering the 3.4 GHz band -3.8 GHz, have shown very satisfactory performances more than -30 dB in terms of reduction of mutual coupling between the antennas constituting our system. MIMO diversity parameters, such as Envelope Correlation (ECC), Diversity Gain (DG), and total efficiency, are also studied for each proposed MIMO system.

To achieve this goal, this paper proposes to use the Linear Parameter Varying approach to design an Active Fault Tolerant Control for wind turbines. This Active Fault Tolerant Control is integrated with a Fault Detection and Isolation approach. Fault detection is based on a Linear Parameter Varying interval predictor approach while fault isolation is based on analysing the residual fault signatures. To include fault-tolerance in the control system (already available in the considered wind turbine case study based on the well known SAFEPROCESS benchmark), the information of the Fault Detection and Isolation approach block is exploited and it is used in the implementation of a virtual actuator and sensor scheme. The proposed Active Fault Tolerant Control is evaluated using fault scenarios which are proposed in the wind turbine benchmark to assess its performance. Results show the effectiveness of the proposed Active Fault Tolerant Control approach in faulty situation. © IMechE 2021.},

abstract = {The aim of this study is to develop a new observer-based stabilization strategy for a class of Lipschitz uncertain systems. This new strategy improves the performances of existing methods and ensures better convergence conditions. Sliding window approach involves previous estimated states and measurements in the observer and the control law structures which increase the number of decision variables in the constraint to be solved and offers less restrictive Linear Matrix Inequality (LMI) conditions. The established sufficient stability conditions are in the form of Bilinear Matrix Inequality (BMI) which is solved in two steps. First, by using a slack variable technique and an appropriate reformulation of the Young’s inequality. Second, by introducing a useful approach to transform the obtained constraint to a more suitable one easily tractable by standard software algorithms. A comparison with the standard case is provided to show the superiority of the proposed H∞ observer-based controller which offers greater degree of freedom. The accuracy and the potential of the proposed process are shown through real time implementation of the one-link flexible joint robot to ARDUINO UNO R3 device and numerical comparison with some existing results. © 2021 by the authors.

abstract = {Energy safe is mandatory for all isolated IoT tools, such as in long way roads, mountains, or even in smart cities. If increasing the lifetime of these tools, the rentability of the global network loop becomes more efficient. Therefore, this paper presents a new approach for saving energy inside the source nodes by supervising the state of energy inside each source node and calculating the duty cycle factor. The relationship between these parameters is based on an optimization problem formulation. In this respect, the present paper is designed to propose a new approach that deals with increasing the lifetime of the wireless sensor network (WSN)-attached nodes, as fixed in the application. The newly devised design is based on implementing the IEEE 802.15.4 standard beacon-enabled mode, involving a cluster tree topology. Accordingly, every subgroup is allotted to apply a specifically different duty cycle, depending on the battery’s remaining energy level, which contributes to creating a wide range of functional modes. Hence, various thresholds are defined. Simulation results prove the efficiency of the proposed approach and show the energetic benefit. The proposed flowchart has minimized the consumed energy for the WSN, which improves the battery lifetime and enhances the IoT application’s robustness. Simulations and experiments have been carried out under different conditions and the results prove that the proposed method is a viable solution. © 2021 by the authors.

For the case of modeling uncertainties and/or process dynamic disturbances, conventional feedback linearizing control strategies may fail to be efficient. To design a robust control strategy, meta‐heu-ristic techniques are synthesized with feedback linearization and sliding mode control.

abstract = {Artificial neural networks (ANN) can approximate signals and give interesting results in pattern recognition; some works use neural networks for control applications. However, biological neurons do not generate similar signals to the obtained by ANN. The spiking neurons are an interesting topic since they simulate the real behavior depicted by biological neurons. This paper employed a spiking neuron to compute a PID control, which is further applied to the Van de Vusse reaction. This reaction, as the inverse pendulum, is a benchmark used to work with systems that has inverse response producing the output to undershoot. One problem is how to code information that the neuron can interpret and decode the peak generated by the neuron to interpret the neuron's behavior. In this work, a spiking neuron is used to compute a PID control by coding in time the peaks generated by the neuron. The neuron has as synaptic weights the PID gains, and the peak observed in the axon is the coded control signal. The neuron adaptation tries to obtain the necessary weights to generate the peak instant necessary to control the chemical reaction. The simulation results show the possibility of using this kind of neuron for control issues and the possibility of using a spiking neural network to overcome the undershoot obtained due to the inverse response of the chemical reaction. © 2021, Association for Scientific Computing Electronics and Engineering (ASCEE).

Managing the power flow from various energy sources must be made with restrictions to several conditions and other necessities. Therefore, this paper aims at finding the valuable solution for feeding the necessary parts with the needed power and extracting from other the essential energy. The solution is based on the intelligent tool as the fuzzy logic controller. An energy procedure based on this regulator aims at controlling all the equipment's in this isolated Mini-Grid under study. A mathematical model was first built for showing this mini-grid, the model is validated and then tested using the Matlab Simulink platform for having the results. © 2021 IEEE.},

abstract = {A photovoltaic-powered electric vehicle is a complex system that necessitates the use of a high-performance control algorithm. This paper aims to boost the performance of a photovoltaic system by employing a suitable algorithm to control the power interface. The main goal is to find an effective and optimal control law that will enable the photovoltaic generator (GPV) to generate the maximum amount of power possible. The main facts dealt with in this article are the mathematical simulation of the photovoltaic system, its function, and its characteristics, considering the synthesis of the step-up converter and the analysis of the maximum power point tracking algorithm. This study examines and compares two control techniques for extracting full power from the solar energy system. These two techniques are the classical 'perturbation and observation' (PO) method and the intelligent solution 'particle swarm optimization (PSO) method.' The PSO solution is tested for two versions: the online PSO version and the table PSO version. The Simulink/MATLAB tool is used for simulation and comparative experiments based on the performance metrics provided. The study revealed that smart technology delivers improved efficiency than the classic edition. © 2013 IEEE.},

abstract = {Waterleakage detection and localization in distribution networks pipelines is a challenge for utility companies. For this purpose, thermal Infrared Radiation (IR) techniques have been widely applied in the literature. However, the classical analysis of IR images has not been robust in detecting and locating leakage, due to presence of thermal anomalies such as shadows. In this study, to improve the detection and location accuracy, a digital image processing tool based on multitemporal IR is proposed. In multitemporal IR analysis, the variation of soil's temperature due to field temperature can be obtained; and hence; estimating variations due to water leakage would be more accurate. An experimental setup was built to evaluate the proposed multitemporal IR water leak detection method. In order to consider the temporal temperature variation due to water leakage and mitigate the field temperature effects, a luminance transformation of the IRimages was introduced. To determine the temporal temperature variation of the soil's surface due to the leakage, several metrics have been considered such as the difference, the ratio, the log-ratio and the coefficient variation (CV) images. Based on the experimental results, the log-ratio and the CVimages were the most robust metrics. Then, based on log-ratio or the CV image, a temporal variation image (TVI) that traduces the temporal IR luminance variation was introduced. The analysis of the TVI image showed that the CV image is less noisy than the log-ratio image, and can more accurately locate the leakage. Finally, based on TVI histogram, a threshold was defined to classify the TVI image into leakage/non-leakage areas. Results showed that the proposed method is capable of accurately detecting and locating water leakage, which is an improvement to the false detections of spatial thermal IR analysis. © 2013 IEEE.},

abstract = {Speckle filtering in synthetic aperture radar polarimetry (PolSAR) is essential for the extraction of significant information. In this study, the authors introduced a hybrid iterative filtering scheme. The proposed iterative filter is initialized by a polarimetric filter ensuring a high speckle reduction level. Then, to enhance the spatial details, the iterative filter is applied for few iterations. The key parameter $b_k$ which traduced the variability of the pixels has been studied. An expression that takes into account the following important numerical considerations is proposed. 1) The variability of the pixel is measured by coefficient variation (CV) rather than the variance. 2) The statistics are computed using non-local neighborhood instead of local square one. 3) A new normalizing function (i. e. hyperbolic tangent) is implemented. 4) The dynamic of range of $b_k$ is increased by multiplying the CVs of the filtered and the originals images. Comparison with various state of the art PolSAR filters demonstrated the effectiveness of the proposed iterative method. Simulated, one-look and multilook real PolSAR data were used for validation. © 2013 IEEE.},

This new strategy improves the performances of existing methods and ensures better convergence conditions. The observer and the controller are enriched with sliding windows of measurements and estimated states, respectively. This technique allows to increase the number of decision variables and thus get less restrictive and more general LMI conditions. The established sufficient stability conditions are in the form of Bilinear Matrix Inequality (BMI). The obtained constraint is transformed, through a useful approach, to a more suitable one easily tractable by standard software algorithms.

abstract = {Speckle filtering in synthetic aperture radar polarimetry (PolSAR) is essential for the extraction of significant information. In this study, the authors introduced a hybrid iterative filtering scheme. The proposed iterative filter is initialized by a polarimetric filter ensuring a high speckle reduction level. Then, to enhance the spatial details, the iterative filter is applied for few iterations. The key parameter bk which traduced the variability of the pixels has been studied. An expression that takes into account the following important numerical considerations is proposed. 1) The variability of the pixel is measured by coefficient variation (CV) rather than the variance. 2) The statistics are computed using non-local neighborhood instead of local square one. 3) A new normalizing function (i. e. hyperbolic tangent) is implemented. 4) The dynamic of range of bk is increased by multiplying the CVs of the filtered and the originals images. Comparison with various state of the art PolSAR filters demonstrated the effectiveness of the proposed iterative method. Simulated, one-look and multilook real PolSAR data were used for validation.},

abstract = {The recent advancement in synthetic aperture radar (SAR) technology has enabled high-resolution imaging capability that calls for efficient speckle filtering algorithms to preprocess radar imagery. Since the introduction of the Lee sigma filter in 1980, the various versions of the minimum mean square error (MMSE) filter were developed, focusing essentially on how to estimate the processed pixels. For instance, the iterative MMSE (IMMSE) filter that is commonly initialized by the boxcar filter maintains the initially filtered homogeneous areas and corrects the initially blurred spatial details after a few iterations. In this article, an effort is made to enhance the performance of the IMMSE filter in terms of speckle reduction and spatial detail preservation by refining the choice of the initial filter, optimizing its parameters, and improving the estimation of local statistics. Compared with the basic version, results showed that the improved iterative filter considerably enhanced the filtering criteria. When the improved iterative filtering process was initialized by the nonlocal mean filter, for few iterations, the filtering performances were improved. Simulated, airborne (ESAR, Oberpfaffenhofen Germany) and spaceborne (Sentinel 1, Palm Jumeirah Dubai UAE) SAR data were used to assess the filtering performances of the studied filters.},

The UN FAO has reported that food production would need to be increased by approximately 70 percent to feed this increased population. Therefore, to ensure high yields and farm profitability, it is very important to improve agricultural productivity. In this sense, the technology of the Internet of Things (IoT) has become the key road towards novel practice in agriculture. In the agriculture sector, climate change is also a major concern. A solution to completely satisfy the requirements of automated and real-time monitoring of environmental parameters such as humidity, temperature and rain is proposed in this paper. The proposed platform, which collects environmental data (temperature, humidity and rain) over a period of one year was tested on a real farm in Tunisia. The results show that the proposed solution can be used as a reference model to meet the requirements for large-scale agricultural farm calculation, transmission and storage. © 2020 IEEE.},

abstract = {This chapter focuses on the study of the effects of design variables on the permanent magnet (PM) demagnetization of a permanent magnet synchronous motor (PMSM) using a two-dimensional (2D) finite element analysis (FEA) software package. The aim is to investigate the shape design of a permanent magnet considering the effect of the pole embrace and the magnet thickness on demagnetization by using finite element method (FEM). As a result, it is shown that pole embrace and magnet thickness are the most important geometrical dimensions of the PMSM in terms of demagnetization fault. The effects of demagnetization fault on the magnetic field distribution, the back electromotive force (EMF) induced, and the electromagnetic torque of PMSM are examined. Using the simulated model, a technical method, based on fast Fourier transform (FFT) analysis of induced voltage and electromagnetic torque, is exported to detect the demagnetization fault. Finally, the technique used and the obtained results show clearly the possibility of extracting signatures to detect and locate faults and verifying the effectiveness of the analysis results. © 2020, Springer Nature Singapore Pte Ltd.},

This design with 45×45 mm dimension is then integrated in close proximity at distance of 10 mm with an ultra wide band (UWB) antenna to enhance it' s performances around a 3.5 GHz operating frequency. Simulation results ensure that filter geometry provides the advantage of the angular stability up to to 45? and also polarization modes independency (transverse electric (TE) and transverse magnetic (TM)). In addition, enhancement in antenna radiation pattern characteristics is enhanced especially when the FSS filter layer is integrated at a very close distance from the radiator. Moreover, antenna gain was improved to 3.22 dBi, adaptation of antenna port (S11) was increased to-53.26 dB and antenna bandwidth reduction to 1.7 GHz is also detected. All these performances make the proposed design as a good choice used to shield signals in UWB wireless applications especially for connected object in 5G.

abstract = {In this article, a new form of UWB (ultra-wide-band) antenna operating to the desired specifications, obtained from a base antenna to which some modifications are made. The proximity of the antennas causes a mutual coupling phenomenon thus generating an apparent modification of their characteristics. It is therefore crucial to have the minimum level of insulation with a small possible separation distance between the antennas to ensure efficient operation of our multiple input and multiple output (MIMO) system. The separation spacing between the antennas is close to 0.15λ0 (λ0 is the wavelength in free space), where the coupling can be very weak. To overcome this weakness, two efficient methods are applied to minimize mutual coupling in a four-element MIMO antenna, such as the use of the neutralization line and the use of split ring resonator metamaterial (SRR). The objective of our paper is, on the one hand the design of UWB antenna, and on the other hand to minimize the coupling between four UWB-MIMO antennas using the two methods of isolation mentioned above. A coupling minimization of more than 15 dB is obtained using the neutralization line and more than 20 dB with the use of metamaterial while maintaining the operating band and radiation specifications of the MIMO antennas. © 2020 ASTES Publishers.

The unit cell proposed design based on Frequency Selective Surface (FSS) is made of a square loop element glued to a thin substrate to ensure a band-stop filtering behavior. This geometry is symmetrical providing the advantage of polarization independency and exhibiting angular stability up to 45◦ for both Transverse Electric (TE) and Transverse Magnetic (TM) modes.

In case interval observers cannot be synthesized straightforwardly, so as to obtain a stable and non-negative estimation error, it is shown that a change of coordinates allows to overcome this problem. The proposed methodology allows to bound fractional systems trajectories when the whole past is unknown but can be bounded.

abstract = {A Wireless Sensor Network (WSNs) consists of spatially distributed autonomous sensor nodes to monitor physical or environmental conditions. The major advantage of WSN is that it can be installed in harsh environment such as in volcanic eruption, seismic regions, battlefield and forest, etc. The sensor nodes are generally battery-powered devices, the key task in WSN is to reduce the energy consumption of nodes so that the lifetime of the network can be augmented. Energy efficiency and information gathering is a major concern in many applications of WSNs. Many techniques have been developed till now in order to achieve an energy efficient network. Hierarchical clustering is an effective method to save energy in WSNs. Some of the most common energy-efficiency sensor networks protocols is Low Energy Adaptive Clustering Hierarchy (LEACH) as source. In this paper, we propose Threshold sensitive Low Energy Adaptive Clustering Hierarchy for Wireless Sensor Networks (T-LEACH). This last considers the node's heterogeneity of nodes and residual energy for choosing the optimal cluster head (CH). The simulation results have clearly shown that T-LEACH reduces the node's energy consumption, improves the network lifetime and packet transfer ratio. © 2020 IEEE.},

The starting antenna for our study is a classic rectangular patch antenna. Our first concern, to meet the requirements of our specifications, would be to broaden the bandwidth. The logical continuation of our methodological approach, consists in designing unit cells whose resonant frequencies are well in agreement with the applications to the band X. In order to ensure the effectiveness of our system of emission reception, we studied the application of metamaterials to the design of MIMO antennas for miniaturization and performance. The distance between the elements is small and close to 0.09 λo (wavelength in free space), where the coupling can be very strong. The application of these materials has contributed to the increasing of the antenna efficiencies in terms of reflection and transmission coefficient. To confirm our proposed technique using metamaterial, MIMO antennas are simulated and discussed in detail in terms of isolation in order to increase the transmission rate in systems using 5G. © 2020 IEEE.},

For the fault detection purpose, the generic model in natural (or integral) causality is apt to design the COG observers in Luenberger forms. Compared with classical observers-based fault detection, the developed scheme allows to get graphical representation taking in to account the physical aspects (the transit of information and the energy transfer) related to the system mechanism. Owing to energetic and structural aspects, the COG observer gain is determined via causal manipulations (causal loops, causal paths.. etc). The relevance of the suggested framework is proved through the simulation results on the hydraulic system with two tanks. © 2020 IEEE.},

abstract = {This work presents fault-tolerant control of two-time-scale systems in both linear and nonlinear cases. An adaptive approach for fault-tolerant control of singularly perturbed systems is used in linear case, where both actuator and sensor faults are examined in the presence of external disturbances. For sensor faults, an adaptive controller is designed based on an output-feedback control scheme. The feedback controller gain is determined in order to stabilize the closed-loop system in the fault-free case and vanishing disturbance, while the additive gain is updated using an adaptive law to compensate for the sensor faults and the external disturbances. To correct the actuator faults, a state-feedback control method based on adaptive mechanism is considered. The both proposed controllers depend on the singular perturbation parameter$$ε $$ leading to ill-conditioned problems. A well-posed problem is obtained by simplifying the Lyapunov equations and subsequently the controllers using the singular perturbation method and the reduced subsystems yielding to an$$ε $$-independent controller. In the nonlinear case, an additive fault-tolerant control for nonlinear time-invariant singularly perturbed system against actuator faults based on Lyapunov redesign principle is presented. The full-order two-time-scale system is decomposed into reduced slow and fast subsystems by time-scale decomposition using singular perturbation method. The time-scale reduction is carried out by setting the singular perturbation parameter to zero, which permits to avoid the numerical stiffness due to the interaction of two different dynamics. The fault-tolerant controller is computed in two steps. First, a nominal composite controller is designed using the reduced subsystems. Second, an additive part is appended to the nominal controller to compensate for the effect of an actuator fault. In both cases, the Lyapunov stability theory is used to prove the stability provided the singular perturbation parameter is sufficiently small. The designed control schemes guarantee asymptotic stability in the presence of additive faults. Finally, the effectiveness of the theoretical results is illustrated using numerical examples. © 2020, Springer Nature Singapore Pte Ltd.},

An unknown input observer (UIO) is designed here to estimate faults and to generate residuals. Based on the descriptor approach, we elaborate an augmented system which considers faults as auxiliary.

The convergence of the observer is analyzed in terms of Lyapunov quadratic stability by generating linear matrix inequalities (LMIs).

abstract = {The aim of this paper is to develop a new observer-based stabilization strategy for a class of Lipschitz uncertain systems. This new strategy improves the performances of existing methods and ensures better convergence conditions. The observer and the controller are enriched with sliding windows of measurements and estimated states, respectively. This technique allows to increase the number of decision variables and thus get less restrictive and more general LMI conditions. The established sufficient stability conditions are in the form of Bilinear Matrix Inequality (BMI). The obtained constraint is transformed, through a useful approach, to a more suitable one easily tractable by standard software algorithms. Numerical example is given to illustrate the performances of the proposed approach. Copyright © 2020 The Authors. This is an open access article under the CC BY-NC-ND license},

Secondly, it aggregates this clusters to obtain final results using Ncut spectral clustering. We call it as FCE-CF approach. This proposed method is guided by cluster validity index kappa.

Abstract 
 
The work presented in this thesis is part of the study of the effectiveness of CRONE 
control with anticipative effect in the problems of tracking and control for monovariable 
and multivariable systems. The anticipation objective is to design a control algorithm that 
minimizes a quadratic error between the reference and the output of the system and at 
the same time achieve a good level of the control signal. The proposed solution combines a 
robust feedback control with a feedforward control. The feedforward action uses optimality 
criteria and an anticipative filter which is designed in the frequency domain using a mix 
of H2 et H∞ constraints. The reduction of the number of parameters of the anticipative 
filter by using a slower sampling period for the anticipative filter is treated. Academic 
examples highlight the theoretical developments. A practical application on a hydraulic 
control system has shown the efficiency of the developed approach.

Stability analysis is performed based on the Lyapunov-Krasovskii theory. Observers are dedicated either to state estimation or to fault detection. Two methods of diagnosis are applied for fault detection and isolation. For LPV systems, the developed approaches have been applied to two examples of real processes ; a truck trailer and a Polymer Electrolyte Membrane Fuel Cell (PEMFC). Then, two types of Fault Tolerant Control (FTC) are used to maintain the stability of delayed SPS even in the presence of faults such as trajectory tracking (PI control) and output-feedback control. Simulation examples illustrate these contributions.

An adaptive fractional order with time delay observer is then constructed to estimate the fault by providing an on-line estimation algorithm. The convergence criteria of this observer is expressed via linear matrix inequalities (LMIs) by the use of a specific Lyapunov function considering the continuous frequency disturbed model. The validity of the fault detection and estimation technique is shown by a numerical example.},

abstract = {A discrete-time robust controller design method is proposed for optimal tracking of future references in preview systems. In the context of preview systems, it is supposed that future values of the reference signal are available a number of time steps ahead. The objective is to design a control algorithm that minimizes a quadratic error between the reference and the output of the system and at the same time achieves a good level of the control signal. The proposed solution combines a robust feedback controller with a feedforward anticipative filter. The feedback controller's purpose is to assure robustness of the closed-loop system to model uncertainties. Any robust control methodology can be used (such as μ-synthesis, qft, or crone control). The focus of this paper will be on the design of the feedforward action in order to introduce the anticipative effect with respect to known future values of the reference signal without hindering the robustness achieved through the feedback controller. As such, the model uncertainties are taken into account also in the design of the feedforward anticipative filter.

In case interval observers cannot be synthesized straightforwardly, so as to obtain a stable and non-negative estimation error, it is shown that a change of coordinates allows to overcome this problem. The proposed methodology allows to bound fractional systems trajectories when the whole past is unknown but can be bounded.

The communication network may introduce time delays while exchanging data among sites connected to the network medium (i.e., the data acquisition site and the remote plant site). Two different approaches are presented in this paper. The first one uses a conventional estimator-based predictor when the uncertainties are supposed to be known. In the case of unknown but bounded uncertainties by known bounds, an interval estimation-based predictor evaluating the set of admissible values for the state is investigated. The state prediction techniques are used to compensate the effect of network-induced delays. Simulation results are introduced to illustrate the efficiency of the proposed techniques. © 2019 IEEE.},

abstract = {Predictive control has become very popular with practitioners of automatic control due to its design simplicity and relatively good performances. Recent efforts have concentrated into improving the robustness of predictive controllers. In this paper, a method for the tuning of generalized predictive controllers (GPC) using desired closed-loop transfer functions for robust design is evaluated in the context of preview systems supposing that future values of the reference signal are available a number of time steps ahead. This information can be used to reduce the error between the reference signal and the measured output by adding an anticipative action to the controller. The robust predictive control method investigated here reveals some surprising limitations when evaluated in an anticipative context (on a preview system), although satisfactory results are obtained in an non-anticipative context. First the performances and robustness of the obtained GPC controller are validated in an non-anticipative context. Then, it is shown that an equivalent feedforward filter appears when anticipation is added, which can have bad effects on the system performances. An academic simulated example is used to validate our conclusions. © 2019 Walter de Gruyter GmbH, Berlin/Boston. All rights reserved.},

abstract = {It is well known that, in some industrial process identification situations, measurements can be collected from closed-loop experiments for several reasons such as stability, safety, and performance constraints. In this paper, we investigate the problem of identifying continuous-time fractional closed-loop linear parameter varying systems. The simplified refined instrumental variable method is developed to estimate both coefficients and differentiation orders. This method is established to provide consistent estimates when the output and the scheduling variable are contaminated by additive measurements noise. The proposed scheme is evaluated in comparison with other approaches in terms of a simulation example. © The Author(s) 2019.},

abstract = {Since their integration in a vast range of applications, including advanced manufacturing plants, advanced communication, smart power grids and transportation networks, Networked control systems (NCS) became an interesting subject of many studies. NCS is a set of entities communicating and exchanging data via a network, which makes its analysis and synthesis complex. To solve this problem, Petri nets and their modeling potential are used for modeling manufacturing plants as discrete event systems. This powerful method of modeling based on Colored Petri nets (CPN) able to provide a very compact way and a well-Adapted and progressive framework for modeling and analysis complex systems in which competition, synchronization, resource sharing and parallelism are present. Our work concerns facilitating the practical use of CPN for designing of network. A model for the Ethernet switch with two scheduling policies (Static Priority, Weighted Round Robin (WRR)) is proposed. © 2019 IEEE.},

abstract = {The rapid development of Internet of Thing (in industrial sectors has remarkably increased the number of communicating physical assets and the complexity of interaction between heterogeneous devices. Physical assets and products are becoming more and more mobile, shared, autonomous and computerized and far more resources are no more owned but rent by the industrial operators. Industries have entered in the era of communicating objects and rental of physical assets for productive and economic efficiencies. In this evolutionary and reconfigurable context, classical centralized and deterministic control methodologies based on request/response are no more satisfying to tackle the change of communicating asset paradigm. Asset management is getting closer to the relationship management in a social group of individuals from the same organization or coming from external contractors. In this paper, we propose an innovative approach of object interactions and services management in Industrial IoT, which takes benefits from social relationship paradigm and social group behaviours. The paper describes a unified socio mimetic model for industrial communicating object interactions resulting from a synthesis of the major sociological approaches studied from the sociologic and scientific communities research works. The different principles of social interaction are transposed to industrial communicating objects to shape a new concept of Sociable Industrial Communicating Object, and elementary industrial use cases are discussed. © 2019 IEEE.},

abstract = {The patch antenna is a critical element in a radio transmission chain which becomes one of the best antenna structures, because of it's low manufacturing cost and compact design and the use of metamaterial structures has been become attractive in the electromagnetic structures community and antenna. In this paper, method is proposed for reducing the inevitable mutual coupling in a two-element Multiple-Input Multiple-Output (MIMO) antenna network that are extremely close to each other. In order to reduce this coupling, a periodic linear network formed by 4 units square ring resonator (SRR) is inserted between the two ultra wide band (UWB) antennas designed, satisfying the required specifications and obtained from an antenna, based on the introduction of certain modifications. In fact, we have studied the performance of a mass-modified patch antenna consisting of FR-4 which is 25 × 30 × 1.6mm3 a type of substrates. The bandwidth ranges from 3 GHz to 18 GHz in which has a bandwidth of about 15GHz. Simulations performances show that the gain in isolation from antennas with metamaterials is superior to 25 dB in the two frequency bands: 3 to 6 GHz and 12 to 13 GHz. This gain is also greater than 10 dB in the rest of the operating frequency band. © 2019 IEEE.},

abstract = {This paper presents the fault tolerant control (FTC) of a flexible joint robot using singular perturbation method in order to compensate for the lost performance due to the occurrence of actuator fault and the uncertainty. This FTC is based on Lyapunov redesign principle. The singular perturbation method is used to reduce the dynamic model of the flexible joint robot in a fast and slow subsystem. The time scale reduction of the flexible joint model is carried out when their joint stiffness is large enough and the singular perturbation parameter is set to zero. The fault-tolerant control structure in this paper is based on two parts. The first term described the composite control for the system without defect and without uncertainty which represents the sum between slow and fast controllers. While the second term of the fault tolerant command describes additive control designed to compensate for the fault effect of the actuator on the uncertain system. The additive approach is based on the Lyapunov theorem, which guarantees asymptotic stability despite the presence of actuator defects and the parametric uncertainty. The theoretical results are applied on a robot manipulator with a single flexible joint. © 2019 Aymen Elghoul et al., published by Sciendo 2019.},

abstract = {This brief discusses a new linear matrix inequality (LMI)-based $boldsymbol mathcal Hboldsymbol ınfty $ filter for a class of one-sided Lipschitz discrete-time systems. Due to the introduction of a sliding window of delayed measurements, new LMI conditions are proposed. Indeed, the previous measurements allow increasing the number of decision variables in the LMIs, which render it more general and less conservative than those established by using the standard Luenberger structure of the filter. Analytical and numerical comparisons are provided to demonstrate the superiority of the proposed filter with respect to the standard one. Finally, simulation results and real-time implementation have been presented to illustrate the performances of the new filter. © 2004-2012 IEEE.},

abstract = {A discrete-time robust controller design method is proposed for optimal tracking of future references in preview systems. In the context of preview systems, it is supposed that future values of the reference signal are available a number of time steps ahead. The objective is to design a control algorithm that minimizes a quadratic error between the reference and the output of the system and at the same time achieves a good level of the control signal. The proposed solution combines a robust feedback controller with a feedforward anticipative filter. The feedback controller's purpose is to assure robustness of the closed-loop system to model uncertainties. Any robust control methodology can be used (such as μ-synthesis, qft, or crone control). The focus of this paper will be on the design of the feedforward action in order to introduce the anticipative effect with respect to known future values of the reference signal without hindering the robustness achieved through the feedback controller. As such, the model uncertainties are taken into account also in the design of the feedforward anticipative filter. The proposed solution is validated in simulation and on an experimental water tank level control system. © 2019 American Society of Mechanical Engineers (ASME). All rights reserved.},

abstract = {Predictive control has become very popular with practitioners of automatic control due to its design simplicity and relatively good performances. Recent efforts have concentrated into improving the robustness of predictive controllers. In this paper, a method for the tuning of generalized predictive controllers (GPC) using desired closed-loop transfer functions for robust design is evaluated in the context of preview systems supposing that future values of the reference signal are available a number of time steps ahead. This information can be used to reduce the error between the reference signal and the measured output by adding an anticipative action to the controller. The robust predictive control method investigated here reveals some surprising limitations when evaluated in an anticipative context (on a preview system), although satisfactory results are obtained in an non-anticipative context. First the performances and robustness of the obtained GPC controller are validated in an non-anticipative context. Then, it is shown that an equivalent feedforward filter appears when anticipation is added, which can have bad effects on the system performances. An academic simulated example is used to validate our conclusions. © 2019 Walter de Gruyter GmbH, Berlin/Boston. All rights reserved.},

The general theme of this thesis concerns the optimization of diagnostic module 
performance and therefore fault-tolerant control of stochastic systems. 
In the first part, a robust residue generation method based on the RTSK filter for a stochastic 
system with a single actuator or sensor fault and the ARThSKF filter for a stochastic system 
with simultaneous actuator and sensor faults in the presence of unknown inputs is performed. 
In the second part, a new method of residual evaluation using an adaptive threshold based on the 
Bayes test and gray theory is developed to ensure optimal performance in terms of detection time, 
false alarm rate and non-detection rate . A new isolation method based on double localization 
is presented. 
Finally, the optimal diagnostic module is used to apply a corrective law based on the additive and 
LQG method. The proposed method guaranteed the stability of the system after accommodation 
and verifies the speed of performance recovery.

Abstract 
This research work aims at studying the identification of fractional Linear Parameter varying Systems in continuous-time. At first, two classes of methods are developed : the first one is based on the least squares methods, and the second one is based on the instrumental variable method. Thus, two cases have been considered. Firstly, all the fractional derivation orders are assumed to be a priori known and only the coefficients of the fractional differential equation of the continuous time LPV model are estimated. Secondly, both fractional differential equation coefficients and differentiation order are estimated. Then, the scheduling variable is supposed to be measurable. A method is developed, dedicated to estimate the parameters as well as the fractional derivation orders of the continuous time linear parameter varying model. The bias compensated principle is introduced based on the instrumental variable method. Simulations illustrate the performance of the proposed approaches.

Abstract : This thesis topic concerns the planning of trajectories of a mobile multi-robot 
system in a dynamic environment. The planning study was conducted in a "barrier-free" and 
"with obstacle" environment, based on the artificial potential field technique. This technique 
makes it possible to obtain attractive and repulsive force profiles adapted to the needs of the 
application and leads to optimal trajectories. Also, for multi-robot mobile systems, one of the 
main technical considerations is the technique used to coordinate the movements of different 
robots. So, three types of planning architecture are proposed: decentralized architecture, 
centralized architecture and hierarchical architecture.

First, the full order system will be controlled using $epsilon$-dependent control law. The corresponding Lyapunov equation is ill-conditioned due to the presence of slow and fast phenomena. Secondly, a time-scale decomposition of the Lyapunov equation is carried out using singular perturbation method to avoid the numerical stiffness. A composite control law based on local controllers of the slow and fast subsystems is also used to make the control law $epsilon$-independent. The designed fault tolerant control guarantees the robust stability of the global closed-loop singularly perturbed system despite loss of effectiveness of actuators. The stability is proved based on the Lyapunov stability theory in the case where the singular perturbation parameter is sufficiently small. A numerical example is provided to illustrate the proposed method.},

Abstract 
The analysis and synthesis of dynamic systems has undergone significant development 
in recent decades, as illustrated by the considerable number of published works in 
this field, and continue to be a research theme regularly explored. While most of the work 
concerns linear and nonlinear continuous-time systems, few results have been established 
in the discrete-time case. This thesis deals with the observation and control of a class of 
nonlinear discrete-time systems. At first, the problem of state observer synthesis using a 
sliding window of measurements was discussed. Non-restrictive stability and robustness 
conditions have been deduced. Thus, two classes of discrete time nonlinear systems have 
been studied : Lipschitz systems and one-side Lipschitz systems. Then, a dual approach 
was explored to derive a stabilizing control law based on observer-based state feedback. 
The conditions for the existence of an observer and a controller stabilizing the studied 
classes of nonlinear systems were expressed in term of LMI. The effectiveness and validity 
of the proposed approaches are shown through numerical examples.

Abstract 
 
This work deals with the design of a fractional PID and CRONE controller for nonlinear 
systems using the Singular Perturbations approach and the Multimodel approach. 
Definitions and main properties of the fractional operators are given. So, the approximation 
method allowed us to apply the first generation CRONE control in the case of a singularly 
perturbed system with two slow and fast dynamics. 
Then, design methods of robust controller P IαDβ have been studied in order to propose a 
fractional control strategy using the singular perturbation method for a nonlinear system. This 
control ensure the tracking of a desired fractional model as well as to have a good rejection of 
disturbance. Then, a study of a nonlinear hydraulic process has illustrate this approach. 
Finally, the first-generation CRONE control is proposed for a nonlinear process approximated 
by first-order multimodeles, the results were hopeful to implement a new control approach for 
this type of systems using here the non integer P Iα regulators.

abstract = {State estimation of stochastic discrete-time linear systems subject to unknown inputs has been widely studied, but few works take into account disturbances switching between unknown inputs and constant biases. We show that such disturbances affect a networked control system subject to deception attacks on the control signals transmitted by the controller to the plant via unreliable networks. This paper proposes to estimate the switching disturbance from an augmented state version of the intermittent unknown input Kalman filter. The sufficient stochastic stability conditions of the obtained filter are established when the arrival binary sequence of data losses follows a Bernoulli random process. © 2018 Karim Chabir, published by Sciendo.},

abstract = {This paper deals with H∞ observer-based controller design for a class of discrete-time systems with Lipschitz nonlinearities. Usually, the observer-based control synthesis for the considered class of systems leads to the feasibility of a Bilinear Matrix Inequality (BMI). Since, solving a BMI constraint has been an NP-hard optimization problem, then linearizing this constraint to get a convex one is an interesting issue because Linear Matrix Inequalities (LMIs) are easily tractable by numerical softwares (LMI Toolboxes,.). Hence, the aim of this paper is to develop a new Linear Matrix Inequality (LMI) condition, ensuring the H∞ asymptotic convergence of the observer-based controller. Due to the introduction of a slack variable technique, the usual BMI problem is equivalently transformed to a more suitable one, which leads to less conservative and more general LMI condition compared to the existing methods in the literature. Conjointly to the slack variable technique, the Lipschitz property and the Young's relation are used in a reformulated way to obtain additional decision variables in the LMI. In the aim to further relax the proposed LMI methodology, sliding windows of delayed states and measurements are included in the structures of the controller and the observer, respectively. The obtained LMI is more general and less conservative than the first one, which can be viewed as a particular solution. To show the effectiveness and superiority of the proposed methodology, some numerical examples and comparisons are provided. © 2018 European Control Association},

The main objective of the proposed method is to improve the transient time response, the stability margin, the robustness and the load disturbance rejection capability. All of these performances are tested through simulation examples. © 2018 Inderscience Enterprises Ltd.},

abstract = {This paper presents the problem of robust fault diagnosis and accommodation for a class of linear stochastic systems where simultaneous actuator and sensor faults may occur at a given time. Firstly, based on Augmented Robust Three stage Kalman filters (ARThSKF) we obtained both the fault estimation and the residual signal. Then, residual evaluation is achieved by making use of an adaptive threshold adjustment algorithm based on the grey theory. Obtained results show that the false-alarm rates and the missing alarm rates are minimized by the developed method; also this approach detects small or incipient faults more effectively than the classical robust fault detection algorithms with fixed thresholds. Finally, an additive control input is introduced for cancelling out the fault's effect on the system. We evaluate our proposal through simulation and we demonstrate its feasibility. © 2018 IEEE.},

abstract = {This paper generalizes Kalman filtering with an intermittent unknown input problem to be left invertible discrete-time stochastic linear systems with zero, one, or more structural delays. Contrary to the state filtering\textendashbased system inversion where the unknown input vector is reconstructed with a time delay that is equal to the structural delay of the plant, we propose an optimal state filtering by reconstructing some linear combinations of the unknown input vector with a time delay less than the structural delay. Designed under a sequential unknown input decoupling constraint, which has never been previously studied in the literature, all presented filters are very computationally efficient. The proposed state filtering is used to solve the autonomous distributed state filtering problem in large-scale networked control systems when the unknown input vector represents interactions between subsystems and when each subsystem receives intermittent information about the interaction from unreliable networks. The stochastic stability conditions of the extended intermittent unknown input Kalman filter are established when the arrival binary sequence of packet dropouts follows a random Bernoulli process.

This study focuses on recursive least square and instrumental variable techniques applied to the (1D) and (2D) models. The model of the rotary drum filter is based on different physical laws involved in the filtration phase in order to get a simulator of the filtration process. Besides, many physical parameters rise in the system model and effect enormously the efficiency which should be modelled with precision such as permeability, porosity and viscosity. We use a constructive realization procedure for (2D) systems which may lead to a Fornasini\textendashMarchesini local state-space model to describe the dynamic of the system states. © 2018 The Author(s).},

It is based on detection tests and logical diagnosis analysis for the first principle. At the beginning, a succinct state of art is provided for existing fault detection and diagnosis (FDD) methods. Then, the diagnosis algorithm is proposed: it deals with a BRIDGE approach of FDD for a building system focusing on sensor grids. Sensor faults are diagnosed thanks to detection tests and diagnosis first principle. In addition, this approach provides the possible fault modes including multiple sensor faults. Finally, a series of tests are performed in order to validate the approach. An application example shows the efficiency of the proposed technique: an office setting at Grenoble Institute of Technology. © 2018 Elsevier Ltd},

First, the full order system will be controlled using ε-dependent control law. The corresponding Lyapunov equation is ill-conditioned due to the presence of slow and fast phenomena. Secondly, a time-scale decomposition of the Lyapunov equation is carried out using singular perturbation method to avoid the numerical stiffness. A composite control law based on local controllers of the slow and fast subsystems is also used to make the control law ε-independent. The designed fault tolerant control guarantees the robust stability of the global closed-loop singularly perturbed system despite loss of effectiveness of actuators. The stability is proved based on the Lyapunov stability theory in the case where the singular perturbation parameter is sufficiently small.

Two best known methods of texture measures, always considered as references in image analysis are chosen for comparison: the Local Binary Patterns (LBP) and the Grey Level Co-occurrence Matrix (GLCM). We realized numerous experimentations for analyzing the brain Magnetic Resonance (MR) images in order to demonstrate the interest of our proposition. We used the 3D Brainweb database with two brain MR images sequences, and different levels of noise and intensity non-uniformity. This way accuracy of the three methods is tested in front on the image artifacts. Tests of classification are performed in the same conditions of work by means of the classifier multiclass Support Vector Machines (SVM). Experimental results demonstrate clearly the robustness and the stability of the proposed approach with respect to the noise level, intensity non-uniformity and to different T1- and T2- weighted MR images. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.},

Cyber resilience represents the ability of systems or network architectures to continue providing their intended behavior during attack and recovery. When a cyber attack on the control signal of a networked control system is computed to remain undetectable from passive model-based fault detection and isolation schemes, we show that the consequence of a zero dynamic attack on the state variable of the plant is undetectable during attack but it becomes apparent after the end of the attack. A resilient linear quadratic Gaussian controller, having the ability to quickly recover the nominal behavior of the closed-loop system after the attack end, is designed by updating online the Kalman filter from information given by an active version of the generalized likelihood ratio detector. © 2017, Institute of Automation, Chinese Academy of Sciences and Springer-Verlag GmbH Germany, part of Springer Nature.},

abstract = {This paper deals with H∞ observer-based controller design for a class of discrete-time systems with Lipschitz nonlinearities. Usually, the observer-based control synthesis for the considered class of systems leads to the feasibility of a Bilinear Matrix Inequality (BMI). Since, solving a BMI constraint has been an NP-hard optimization problem, then linearizing this constraint to get a convex one is an interesting issue because Linear Matrix Inequalities (LMIs) are easily tractable by numerical softwares (LMI Toolboxes,.). Hence, the aim of this paper is to develop a new Linear Matrix Inequality (LMI) condition, ensuring the H∞ asymptotic convergence of the observer-based controller. Due to the introduction of a slack variable technique, the usual BMI problem is equivalently transformed to a more suitable one, which leads to less conservative and more general LMI condition compared to the existing methods in the literature. Conjointly to the slack variable technique, the Lipschitz property and the Young's relation are used in a reformulated way to obtain additional decision variables in the LMI. In the aim to further relax the proposed LMI methodology, sliding windows of delayed states and measurements are included in the structures of the controller and the observer, respectively. The obtained LMI is more general and less conservative than the first one, which can be viewed as a particular solution. To show the effectiveness and superiority of the proposed methodology, some numerical examples and comparisons are provided. © 2018 European Control Association},

Since, the resolution of a BMI is a hard task, then it is interesting to search for a convenient way to linearize the obtained conditions.

Thanks to the introduction of a slack variable the presented LMI conditions are more general and less conservative than the existence ones. Indeed, reformulations of the Lipschitz property and Young's relation in a convenient way lead to a more relaxed new LMI.

Firstly, based on Augmented Robust Three stage Kalman filters (ARThSKF) we obtained both the fault estimation and the residual signal. Then, residual evaluation is achieved by making use of an adaptive threshold adjustment algorithm based on the grey theory. Obtained results show that the false-alarm rates and the missing alarm rates are minimized by the developed method; also this approach detects small or incipient faults more effectively than the classical robust fault detection algorithms with fixed thresholds. Finally, an additive control input is introduced for cancelling out the fault's effect on the system. We evaluate our proposal through simulation and we demonstrate its feasibility. © 2018 IEEE.},

It is expected that the minimum of recharge time is related to the fixed station of recharge and this mode is efficient only in fixed cars. However, the real problem is related to the running cars, where it is unacceptable that at the middle of travel, the vehicle is stopped and we cannot found a real station of recharge.

abstract = {The goal of this chapter is to design robust observers for fractional dynamic continuous-time linear systems described by pseudo state space representation. The fractional observer is guaranteed to compute a domain enclosing all the system pseudo states that are consistent with the model, the disturbances and the measurement noise realizations. Uncertainties on the initial pseudo state and noises are propagated in a reliable way to estimate the bounds of the fractional pseudo state. Only the bounds of the uncertainties are used and no additional assumptions about their stationarity or ergodicity are taken into account. A fractional observer is firstly built for a particular case where the estimation error can be designed to be positive. Then, the general case is investigated through changes of coordinates. Some numerical simulations illustrate the proposed methodology. © Springer International Publishing AG 2017.},

An interval observer is designed for both subsystems under the assumption that the measurement noise and the disturbances are bounded. Then, the degradation is modeled as a polynomial whose parameters are estimated using ellipsoid algorithms. Finally, the RUL is predicted based on an interval evaluation of the degradation model over a time horizon. A numerical example illustrates the proposed technique. © 2016 ISA},

abstract = {This paper deals with the path planning problem of a group of autonomous Wheeled Mobile Robots in a very dynamic workspace. The idea consists of considering the system of group of robots as a robot network with decentralized architecture. Each robot plans its trajectory according to its actual position, the position of the other neighbor robots, the position of the obstacles and the position of its target point. So each robot should interact with the other robots in the network to cooperate together in order to plan each robot trajectory. The path planning for every robot is planned based on the potential field approach. The network reacts with the changes of workspace in real time by updating the system equations associated for each robot. The main objective of this work is to avoid collision between robots and obstacles in order to ensure the safety of robots. The solution is tested and simulated with Matlab/Simulink and Solidworks/Simmechanics. © 2017},

abstract = {The problem of modeling and fault detection in an electromechanical system having a graphical representation is considered. For this system's dynamics, motivated by a desire to provide a precise fault detection procedure using a unified energy-based framework, 2 energy-based graphical formalisms are presented and compared: the Hamiltonian Bond Graph and the Causal Ordering Graph. Firstly, easily calculated from the Hamiltonian Bond Graph representation covering the causal energetic paths, the energetic residual generators are systematically deduced by comparing the energy quantity in both normal and faulty situations. Secondly, the causal and structural properties of the Causal Ordering Graph tool can be used to design an observer devoted to fault detection so as to derive directly energy-based residual generators in terms of faults. To highlight the effectiveness and applicability of 2 proposed approaches, simulation results on DC motor are provided and discussed. The performances of these fault detection schemes are compared and discussed in detail with respect to existing methods. Copyright © 2017 John Wiley \& Sons, Ltd.},

Abstract 
This thesis focuses on the decentralized estimation and control for large scale systems. 
The objective is to develop software sensors that can produce a reliable estimate of the variables 
necessary for the interconnected nonlinear systems stability analysis. A decomposition of 
a such large system into a set of n interconnected subsystems is paramount for model simplification. 
Then, taking into account the nature of the subsystem as well as the interconnected 
functions, observer-based decentralized control laws have been synthesized. Each control law is 
associated with a subsystem which allows it to be locally stable, thus the stability of the overall 
system is ensured. The existence of an observer and a controller gain matrix stabilizing the 
system depends on the feasibility of an LMI optimization problem. The LMI formulation, based 
on Luyapunov approach, is elaborated by applying the DMVT technique on the nonlinear interconnection 
function, assumed to be bounded and uncertain. Thus, non-restrictive synthesis 
conditions are obtained. Observer-based decentralized control schemes have been proposed for 
nonlinear interconnected systems in the continuous and discrete time. Robust H1 decentralized 
controllers are provided for interconnected nonlinear systems in the presence of perturbations and 
parametric uncertainties. Effectiveness of the proposed schemes are verified through simulation 
results on a power systems with interconnected machines

Les travaux de recherche pr\'{e}sent\'{e}s dans ce m\'{e}moire portent sur la synth\`{e}se d\'{o}bservateurs intervalles pour la commande tol\'{e}rante aux fautes de syst\`{e}mes incertains. La pr\'{e}sence de d\'{e}fauts, d\'{i}ncertitudes et de perturbations peut provoquer des r\'{e}actions ind\'{e}sirables du syst\`{e}me command\'{e}. Dans ce contexte, nous avons d\'{e}velopp\'{e} deux approches de commande tol\'{e}rante aux fautes bas\'{e}es sur des observateurs intervalles dans le cas o\`{u} les d\'{e}fauts et les incertitudes sont inconnus mais born\'{e}s. La premi\`{e}re approche, dite passive, permet de garantir la stabilit\'{e} du syst\`{e}me en boucle ferm\'{e}e y compris en pr\'{e}sence de d\'{e}fauts actionneurs et/ou composants. La seconde approche, dite active, permet de compenser l\'{e}ffet des d\'{e}fauts et d\'{a}ssurer la stabilit\'{e} et les performances d\'{e}sir\'{e}es du syst\`{e}me. Ces contributions sont valid\'{e}es par des simulations num\'{e}riques. 
 
The research work presented in this thesis focuses on the design of interval observers for fault-tolerant control of uncertain systems. The presence of faults, uncertainties and disturbances in automated systems often causes undesirable reactions. In this context, two approaches of fault tolerant control have been developed based on interval observers in the case where the faults and the uncertainties are unknown but bounded. The first approach is passive and consists in ensuring the closed loop system stability even in the presence of actuator and/or component faults. The second approach, an active one, compensates the fault effect and ensures the system stability and desired performances. These contributions are validated through numerical simulations.},

This new antenna consists of a circular microstrip antenna with ring slot inscribed in a patch resonator and a modified partial ground plane with slots to form a single wide bandwidth. Indeed, we studied the performance of a patch antenna made of FR4epoxy substrates (20×20×1.57). The bandwidths range from [3.6 GHz; 4.9 GHz] for a width of 1.3 GHz and a band of [9.7 GHz; 26.7 GHz] of 17 GHz and for frequencies above 27.9 GHz the bandwidth is of the order of 7.2 GHz.

The fractional observer is guaranteed to compute a domain enclosing all the system pseudo states that are consistent with the model, the disturbances and the measurement noise realizations. Uncertainties on the initial pseudo state and noises are propagated in a reliable way to estimate the bounds of the fractional pseudo state. Only the bounds of the uncertainties are used and no additional assumptions about their stationarity or ergodicity are taken into account. A fractional observer is firstly built for a particular case where the estimation error can be designed to be positive. Then, the general case is investigated through changes of coordinates.

An SDG is usually built based on mathematical equations of process or based on process knowledge as described by piping and instrumentation diagrams, this is a complex and experience-dependent task. This paper introduces a methodology to built the SDG directly from Bond Graph. For the fault detection and isolation purpose, the generic model is able to deduce systematically qualitative fault signatures matrix from the qualitative redundancy relations. Whenever an abnormality was not isolated, a principal component analysis and a back/forward propagation through paths on the SDG model are combined so as to ameliorate the fault isolability. To highlight the efficiency and the performance of the developed algorithm, the multi-energy process case study is provided. © 2017},

abstract = {A communicating object, or connected object, is a key element of the Internet of Things to shift a perceptible real world into a wide digital virtual world known as the cyber-physical system. Knowing that sustainability, safety, and logistic issues are among the significant goals and challenges of modern industrial enterprises, the communicating object can be a relevant concept to guarantee safety performance in logistics and warehouse management. This article presents the impacts and advantages of the communicating object in smart logistics and the design of a communicating object model inspired from Internet of Things European research projects, which controls and monitors safety risks in a hazardous and chemical industrial context. Generic safety-based scenarios are presented, which rely on a set of negotiated interaction mechanisms for storage and picking. The relevant deployment of intelligence in a warehouse management system leads to propose a new concept called "IoT-controlled Safe Area." Our contribution is to bring informational, communicational, and decisional capabilities close to the warehousing physical world thanks to the communicating object. This enables achieving safety assurance with a decrease in the decision-making delay and an increase in the solving efficiency of local and dynamic disruptions, while avoiding inherent shortcomings of the warehouse management system centralization. For this, an industrial implementation is presented. © SAGE Publications.},

This work deals with the frequency-domain and the time-domain analysis of elementary 
fractional systems. 
Firstly, definitions, the main properties of the fractional operators and the different 
representations of fractional system are given. Stability theorem of the non-commensurate 
fractional order system is developed in terms of the fractional order and the pseudo-damping 
factor. Secondly, an overall study of frequency-domain and time-domain performances is done 
for the different elementary transfer function. Also, frequency-domain and time- domain curves 
are established in terms of the fractional order and the pseudo-damping factor. The poles effect 
on the system behavior is treated. In order to obtain a minimum settling time, the optimal 
parameters are determined. Finally, a new approach based on the elementary transfer function 
is developed to design a robust stabilizing fractional order integrator for uncertain first order 
systems with and without integration.

report of this thesis is split into two parts. Firstly, interval observers for switched linear 
systems are developed. These observers provide a guaranteed set that contains all the 
admissible values of the state. The disturbances and the measurement noise are supposed 
to be unknown, but bounded with a priori known bounds. Secondly, approaches of 
diagnosis are proposed based on interval residual generation using interval observers. 
These contributions are validated through numerical simulations.

La th\`{e}se aborde le probl\`{e}me de la diss\'{e}mination des informations li\'{e}es au produit tout au long de son cycle de vie, par l’exploitation du concept de mati\`{e}re communicante. L’objectif g\'{e}n\'{e}ral est de stocker dans la mati\`{e}re communicante ses caract\'{e}ristiques initiales mais aussi l’\'{e}volution de ses propri\'{e}t\'{e}s durant son usage, en \'{e}vitant de les perdre lors par exemple d’une transformation ou d’une destruction d’une partie du mat\'{e}riau. Dans le cadre de cette th\`{e}se, ce principe est appliqu\'{e} dans le domaine des pr\'{e}fabriqu\'{e}s en b\'{e}ton, o\`{u} des n\oeuds de r\'{e}seaux de capteurs sans fil sont int\'{e}gr\'{e}s dans le b\'{e}ton. Ces n\oeuds sont alors utilis\'{e}s pour stocker des informations relatives au cycle de vie du pr\'{e}fabriqu\'{e} et \`{a} sa surveillance sur la phase d’usage. Un nouveau protocole de communication, nomm\'{e} USEE, a \'{e}t\'{e} propos\'{e} et permet de diffuser uniform\'{e}ment les informations dans la mati\`{e}re en consid\'{e}rant qu’elles n’ont pas toutes la m\^{e}me importance. Le protocole USEE \'{e}vite notamment la saturation rapide des m\'{e}moires des n\oeuds de fa\c{c}on \`{a} pouvoir stocker un maximum d’informations diff\'{e}rentes. Ensuite, un protocole de lecture, intitul\'{e} RaWPG, a \'{e}t\'{e} d\'{e}velopp\'{e}. Il est adapt\'{e} \`{a} la r\'{e}cup\'{e}ration d’informations uniform\'{e}ment r\'{e}parties et consomme peu d’\'{e}nergie. Ces deux protocoles ont \'{e}t\'{e} impl\'{e}ment\'{e}s dans le simulateur r\'{e}seau Castalia/OMNeT++ et ont permis de montrer leur int\'{e}r\^{e}t par rapport au contexte applicatif mais aussi par rapport \`{a} d’autres protocoles similaires de la litt\'{e}rature 
 
A new Internet of Things area is coming with communicating materials, which are able to provide diverse functionalities to users all along the product lifecycle. As example, it can track its own evolution which leads to gather helpful information. This new paradigm is fulfilled via the integration of specific electronic components into the product material. In this thesis, ultra-small wireless sensor nodes are used for concrete precast field. Indeed, storage of lifecycle information and data dissemination in communicating materials are very important issues. Therefore, this thesis provides a new protocol (USEE) for storing data by a systematic dissemination through the integrated sensor nodes. It guarantees that information could be retrieved in each piece of the concrete by intelligently managing data replication among each neighborhood of the sensor network. The protocol considers in the same set uniformity storage in the whole network, the data importance level, and the resource constraints of sensor nodes. Then, another new data retrieval protocol (RaWPG) is developed to extract the stored information. Castalia/OMNeT++ simulator is used to evaluate the performances of the proposed protocols},

However, the speckle emerging in SAR images decreases the accuracy of image classification and segmentation. Consequently, it should be filtered correctly. In fact, insufficient averaging generates biased estimates of H/α/A parameters and overaveraging degrades the resolution cell. In this paper, we investigated bias estimation deeply. We enhanced bias compensation of the entropy. The implication of bias for PolSAR data classification has not been studied yet. We demonstrated that bias have an important consequences on PolSAR data classification. Real and simulated data are used.},

abstract = {This paper deals with the adaptive fault tolerant control for linear time-invariant singularly perturbed systems against actuator failures and external disturbances. By time-scale decomposition using singular perturbation method, the full-order system is decomposed into slow and fast subsystems. An ϵ-dependent fault tolerant controller for the global system is first designed. To avoid numerical stiffness, a simplification based on singular perturbation parameter decoupling is secondly carried out using the reduced subsystems and some manipulations of the Lyapunov equations. The resulting control system is fault tolerant in that, it provides guaranteed asymptotic stability in presence of external disturbances when all control components are operational as well as when actuator failures occur. The stability is guaranteed based on the Lyapunov stability theory provided the singular perturbation parameter is sufficiently small. A numerical example is given to illustrate the proposed method, where the efficiency of the developed approach will be compared with a reliable H∞ control technique. © Copyright 2016 Inderscience Enterprises Ltd.},

Two variants of instrumental variables based techniques are proposed to estimate continuous-time parameters of a fractional differential equation linear parameter varying model when all fractional orders are assumed known a priori: the first one is the instrumental variables estimator based in an auxiliary model. The second one is the simplified refined instrumental variables estimator. A comparison study between the developed estimators is done via a numerical example. A Monte Carlo simulation analysis results are presented to illustrate the performances of the proposed methods in the presence of an additive output noise. © 2016 IEEE.},

abstract = {The goal of this work was to use new patch antenna structures based on photovoltaic cells. The radiating patch element of a patch antenna was replaced by a solar cell. Direct Current (DC) generation remained the original feature of the solar cell, but additionally it was now able to receive and transmit electromagnetic waves. It is dedicated to harvesting the energy on the one hand and on the other hand to the RF transmission for telecommunications applications in isolated environments. We propose a square grid with four bus bars around the active area, for this geometry fingers are considered uniform and evenly spaced. A mathematical model which would serve the minimization of power losses of the cell and therefore the improvement in the conversion efficiency was studied. A simulation allowed analyzing the performance of the antenna, with a silicon material, and testing its parameters such as the reflection coefficient (S11), gain, directivity and radiated power. The performance analysis of the solar cell patch antenna was conducted using Advanced Design System (ADS) software. Simulation results for this antenna showed a resonance at a frequency of 14.88 GHz with an effective return loss of -14.77dB and a gain of 5.77dBi. © 2016 Praise Worthy Prize S.r.l. - All rights reserved.},

abstract = {In this paper, a Passive Fault Tolerant Control (PFTC) strategy for Linear Time Invariant (LTI) systems subject to actuator faults is proposed. The idea of this PFTC method is to compute a control law to cope with additive actuator faults using interval observers. The considered system is assumed to be subject to bounded noises and disturbances without any additional assumptions. The FTC is implemented as a state linear feedback control and designed using interval observers techniques. A numerical example shows the efficiency of the proposed technique. © 2016 EUCA.},

abstract = {This paper presents the development of a co-simulation platform of induction motor (IM). For the simulation, a coupled model is introduced which contains the control, the power electronics and also the induction machine. Each of these components is simulated in different software environments. So, this study provides an advanced modeling and simulation tools for IM which integrate all the components into one common simulation platform environment. In this work, the IM is created using Ansys-Maxwell based on Finite Element Analysis (FEA), whereas the power electronic converter is developed in Ansys-Simplorer and the control scheme is build in MATLAB Simulink environment. Such structure can be useful for accurate design and allows coupling analysis for more realistic simulation. This platform is exploited to analyze the system models with faults caused by failures of different drive’s components. Here, two studies cases are presented: the first is the effects of a faulty device of the PWM inverter, and the second case is the influence of the short circuit of two stator phases. In order to study the performance of the control drive of the IM under fault conditions, a co-simulation of the global dynamic model has been proposed to analyze the IM behavior and control drives. In this work, the co-simulation has been performed; furthermore the simulation results of scalar control allowed verifying the precision of the proposed FEM platform. © 2016, Institute of Advanced Engineering and Science.

abstract = {This work describes and validate a Linear Parameter Varying (LPV) model of a real benchmark of wind power system. With a nonlinear model of this process, the use of identification and control concepts for linear model as developed in the literature isn't useful to be used. So that, the nonlinear systems are approximated to Linear Time Invariant (LTI) systems, that is a local approximation of real system. To take account of the nonlinearity and using the linear approaches developed, a linear parameter varying modeling is required. The nonlinear model is transformed to an LPV one using the automated generation method for affine LPV representations. This method consists of generating an LPV model where the nonlinearities are hidden in the vector of parameters. Then, this transformation method is applied to a wind turbine system to get an LPV model for this benchmark system. Finally, the implementation of this LPV benchmark model on Matlab is done and good results are obtained since the LPV simulation responses achieve the nonlinear system model ones that prove the effectiveness and performance of this modeling approach. © 2015 IEEE.},

The non linearity of each subsystem satisfies the Lipschitz condition and the only information about the nonlinear interconnection is that satisfies a quadratic constraint. The key to our work is, in one hand, the reformulation of the Lipschitz condition and the quadratic constraint using the differential mean value to simplify the design of estimation and control matrices gains, and in another hand the use of the Lyapunov's direct method stability analysis. Sufficient conditions that ensure the existence of observer based feedback controller are established in terms of linear matrix inequalities.

abstract = {Security of Cyber-Physical Systems (CPS) against Cyber attacks has become an important challenging research field. False data injections on control and/or measurement signals of a Fault-Tolerant Control System (FTCS) can be treated as detectable virtual actuator or sensor faults. In this case, the FTCS can automatically accommodate false data injections by triggering the controller reconfiguration mechanism at detection time given by the mode-based Fault Detection and Isolation (FDI) algorithm. We show that an intelligent adversary can destabilize the non minimum phase plant of the FTCS by designing a false data injection attack on the control signal while remaining undetectable from any passive FDI algorithm. By using a confining coding method able to block the attack signal on a minimum number of encoded control signals, this paper proposes to transform stealthy false data injections into detectable attacks from an active FTCS based on a switching Linear Quadratic Gaussian (LQG) controller. © 2016 IEEE.},

The present paper is concerned with the merging of the quantitative model (bond graph) and the qualitative reasoning (signed directed graph) and its subsequent is introduced as a new causal graph framework. The integrated model can be involved to generate qualitative fault signatures matrix deduced from the qualitative redundant relations. Compared with the classical bond graph-based monitoring, the proposed mechanism can reduce the number of redundant relations which depend on the qualitative state of known variables and enhance the process monitoring in normal situations as well as in the presence of failures without any need of numerical calculations. The performance of the developed approach is explained using two illustrative examples (systems with single and coupled energies) and discussed in detail with the existing bond graph method.

abstract = {Wheeled mobile robots (WMRs) are of great importance. Therefore, it is necessary to make sure that they are not defected. But, in case of failures, the diagnosis task is very important to predict then solve the problem. The most useful techniques in diagnosis are observers which are based on the observability of the monitored system that is not usually ensured by WMR. Thus, to overcome this drawback, an intelligent cooperative diagnosis algorithm is proposed and tested for a group of mobile robots. The diagnosis algorithm is based on robust adaptive unknown input observer applied on unobservable robot. The local non-observability of each robot is solved by cooperative communication. The idea consists on considering all WMRs as a Large Scale System (LSS) even these robots may have not common task. Then, the LSS is decomposed into subsystems that everyone refers to each robot communicating with its neighbors. Next, a design of cooperative interconnected systems is studied to reassure the new condition of observability. Besides, Fast Adaptive Fault Estimation (FAFE) algorithm is proposed to improve the performances of the fault estimation. Finally, to illustrate the efficiency of the proposed algorithm, a model of three-wheel omnidirectional mobile robot is presented. © 2016 Taylor and Francis Group LLC.},

The main purpose is to design an observer that guarantees the asymptotic stability of the estimate error dynamics and the actuator fault detection. The existence conditions for such an observer are established. The main problem studied in this paper aims at designing observer-based fault detection and isolation. The designed observer enhances the robust diagnosis performance, including rapidity and accuracy, and generates residuals that enjoy perfect decoupling properties among faults. Based on Lyapunov stability theory, the design of the observer is formulated in terms of linear matrix inequalities, and the diagnosis scheme is based on a bank of unknown input observers for residual generation that guarantees fault detection and isolation in the presence of external disturbances.

However, the speckle noise constitutes the main obstacle that hinders these goals and should be filtered. In this paper, based on studies obtained from extensive simulated data sets, we tried to determine how this noise is transmitted to sample eigendecomposition parameters. The dependence between means and variances of sample parameters leads to building their speckle models and to the definition of a bias elimination procedure. We found that sample eigenvalues were affected by multiplicative noise, whereas sample entropy and sample anisotropy were affected by a mixture of multiplicative and additive noise sources. In addition to its versatility, independence to knowledge of the equivalent number of looks and high ability to bias compensation, the proposed bias suppression technique reduced the variance of noise. Simulated and real data as well as the existing theories are used for validation in this paper.},

abstract = {H∞ formulation of the robust fault tolerant control problem for uncertain systems with state time-delays is studied in this paper. A robust control law is then designed in order to automatically compensate actuator and sensor faults, based on a performance index as H∞ model-matching problem. Where, the gain is obtained via Linear Matrix Inequality (LMI) feasibility conditions. Indeed, a new condition is developed to show that the system can be guaranteed to be asymptotically stable in the presence of uncertainties, faults and disturbances based on the Lyapunov-Krasovskii theory. The effectiveness of the design methodology is verified based on a two-stage chemical reactor train with delay recycle streams. © 2015 IEEE.},

abstract = {The paper presents a finite element (FE) based efficient analysis procedure for induction machine (IM). The study based on finite element models (FEM) offers much more information on the phenomena characterizing the operation of electrical machines than the classical analytical models. This explains the increase of the interest for the finite element investigations in electrical machines. This paper attempts to present a dynamic model involving Finite Element Analysis and equivalent circuit simulation together for PWM inverter fed induction motor assisted based on Maxwell 2D and Simplorer. The nonlinear magnetization characteristics have been considered and calculated by FE software Maxwell. The circuits of the inverter are built by using the circuit components in Simplorer environnement. Based on finite element models, this paper studies the influence of the rotor broken bar fault on the IM behavior under various conditions and severity. The comparison of the results obtained by simulation tests allowed verifying the precision of the proposed FEM model. Using the simulated model, this paper presents a technical method based on Fast Fourier Transform (FFT) analysis of stator current and electromagnetic torque to detect the faults of broken rotor bar. The technique used and the obtained results show clearly the possibility of extracting signatures to detect and locate faults. © 2015 IEEE.},

Note that the advance of observer-based fault diagnosis is outlined and the idea of fault class estimation is introduced and studied. A new form of the estimator bloc considered for this purpose is an Unknown Input Observer (UIO). This observer is designed for an unknown input and fault free system, which is obtained by coordinate transformations of original systems with unknown inputs (disturbance) and faults. Stability of the adaptive estimation is provided by a Lyapunov function ending with solving the Linear Matrix Inequalities (LMI). Due to technological advances in the field of electronic devices, the family of robots is of particular interest. To overcome the drawback of robots' model responses when including a fault, a robust observer is adopted for a Pioneer robot to improve the fault estimation and thereafter to repair its trajectory. © 2015, IGI Global.},

Furthermore, faulty data collected in the base station might lead to a wrong judgement. Since the whole system's performance require the accuracy of data, node fault detection is necessary. Motivated by the requirement of fault detection performance, we propose a distributed fault detection algorithm for wireless senor networks based on Hidden Markov Model (HMM). Firstly, a density of probability method is presented to obtain the possibility of translation of state for each node in the network. Then, a HMM is introduced to characterize the tendency of each node to be faulty. Finally, a distributed fault detection algorithm is proposed based on the HMM. Simulation results show that the proposed HMM-based fault detection achieves high detection accuracy. © 2015 IEEE.},

abstract = {This paper deals with robust fractional order PID controller design via numerical optimization. Three new frequency-domain design methods are proposed. They achieve good robustness to the variation of some parameters by maintaining the open-loop phase quasi-constant in a pre-specified frequency band, i.e., maintaining the iso-damping property of the controlled system. The two first methods are extensions of the well-known Monje-Vinagre et al. method for uncertain systems. They ameliorate the numerical optimization algorithm by imposing the open-loop phase to be flat in a frequency band not only around a single frequency. The third method is an interval-based design approach that simplifies the algorithm by reducing the constraints number and offers a more large frequency band with an iso-damping property. Several numerical examples are presented to show the efficiency of each proposed method and discuss the obtained results. Also, an application to the liquid carbon monoxide level control is presented. © 2014, Springer Science+Business Media Dordrecht.},

abstract = {Abstract In this paper, the fractional closed-loop system identification using the indirect approach is presented. A bias correction method is developed to deal with the bias problem in the continuous-time fractional closed-loop system identification. This method is based on the least squares estimator combined with the state variable filter approach. The basic idea is to eliminate the estimation bias by adding a correction term in the least squares estimates. The proposed algorithm is extended, using a nonlinear optimization algorithm, to estimate both coefficients and commensurate-order of the process. Numerical example shows the performances of the fractional order bias eliminated least squares method via Monte Carlo simulations. © 2015 Elsevier Ltd.},

This transfer function is a generalization of the elementary fractional transfer function of the second kind to an arbitrary order. It is written in the canonical form and characterized by a non-commensurate order, a pseudo-damping factor and a natural frequency. Stability and resonance analysis is done in terms of the pseudo-damping factor and the non-commensurate order. Also, an overall study of frequency-domain and time-domain performances of the considered system is done. Therefore many time-domain and frequency-domain curves are presented to help obtaining system parameters for a specified fractional order. Many illustrative examples show the efficiency of this study. Also, an application to the control of a spherical tank is also presented to show the usefulness of this study. © 2014 Elsevier B.V.},

The two first methods are extensions of the well-known Monje-Vinagre et al. method for uncertain systems. They ameliorate the numerical optimization algorithm by imposing the open-loop phase to be flat in a frequency band not only around a single frequency. The third method is an interval-based design approach that simplifies the algorithm by reducing the constraints number and offers a more large frequency band with an iso-damping property. Several numerical examples are presented to show the efficiency of each proposed method and discuss the obtained results. Also, an application to the liquid carbon monoxide level control is presented. © 2014, Springer Science+Business Media Dordrecht.},

Besides, many parameters rise in the system model and effect enormously the efficiency which should be modeled with precision such as permeability, porosity, specific resistance, etc. The improved model developed in this study offer practical means of interpreting experimental data and optimizing the efficiency of the two steps: filtration and attack. The majority of the reported process studies have not made attempts at measuring a full set of measurable parameters.

The basic idea is to eliminate the estimation bias by adding a correction term in the least squares estimates.

abstract = {This work presents an adaptive approach for fault tolerant control of singularly perturbed systems, where both actuator and sensor faults are examined in presence of external disturbances. For sensor faults, an adaptive controller is designed based on an output-feedback control scheme. The feedback controller gain is determined in order to stabilize the closed-loop system in the fault free case and vanishing disturbance, while the additive gain is updated using an adaptive law to compensate for the sensor faults and the external disturbances. To correct the actuator faults, a state-feedback control method based on adaptive mechanism is considered. The both proposed controllers depend on the singular perturbation parameter ε leading to ill-conditioned problems. A well-posed problem is obtained by simplifying the Lyapunov equations and subsequently the controllers using the singular perturbation method and the reduced subsystems yielding to an ε-independent controller. The control scheme, designed based on the Lyapunov stability theory, guarantees asymptotic stability in presence of additive faults and external disturbances provided the singular perturbation parameter is sufficiently small. Finally, a numerical example is presented to demonstrate the effectiveness of the obtained results. © 2015, Kauno Technologijos Universitetas. All rights reserved.},

abstract = {The aim of this paper is to control a dual three induction motor drives under open phases. The DTC is a variable structure control strategy with simplicity, fast response, and tolerance to motor parameter variation, which provides direct control of stator flux and electromagnetic torque by optimally selecting the inverter states in each sampling period. Conventional DTC of dual three induction motor has the limitations of constant duty ratio for every switching period and high torque and flux ripples. To solve these problems and ameliorate the performances of this control method, a fuzzy logic controller is used instead of the hysteresis torque and flux controller to minimizing the torque and flux ripple. The faulted mode of the six phase induction machine leads to torque oscillations and poor tracking behavior. In this way, this paper presents a new modified fuzzy DTC for dual three phase induction motor under open phase. The performance of the modified fuzzy DTC is evaluated through simulation and it is shown to be superior to the conventional DTC in term of minimization the torque and flux ripple under open phase. © 2015 IEEE.},

This stage which makes it possible to carry out hierarchical system decomposition in material elements and/or software does not bring information on modes of failure, their effect, their occurrence and their criticality. It is thus necessary to supplement it by a second analysis taking of account dysfunctions. These two types of analyzes which constitute qualitative analysis, are complementary, and make it possible to model more accurately a networked control system. The goal of this paper is to apply various traditional methods employed in functional specification and operational safety in order to make a relevant qualitative analysis of a networked control system. © 2014 IEEE.},

It is shown that the designed diagnostic algorithm based on reduced order model is close to the one synthesized using the full order system. The developed approach aims at reducing the computational load and the ill-conditioning for stiff residual generation problem.

Therein, a coupled Bond Graph model is used for modeling methodology. A Signed Directed Graph (SDG) is then deduced. Fault detection is later carried out by graph coloring. The localization of the actual fault is performed based on a nonlinear PCA (NLPCA) and back/forward propagations on the SDG. The proposed approach is tested on the thermofluid case study and some simulations are provided. © IFAC.},

In order to apply classical diagnosis methods, such models could be approximated by integer order models, but at the expense of much higher involved parameters and reduced precision. Thus, two diagnosis methods initially developed for integer order models are here extended to handle fractional order models. The first one is the generalized dynamic parity space method and the second one is the Luenberger diagnosis observer. Proposed methods are then applied to a single-input multi-output thermal testing bench and demonstrate the methods efficiency for detecting faults affecting thermal systems. © 2014 Elsevier B.V.},

Then, the commensurate order is estimated along with the differential equation coefficients using a non linear optimization technique combined to the ffocls algorithm (co-ffocls). Under some assumptions on the distributional properties of additive noises and the noise-free input signals, the developed estimators give consistent results. Hence, the noise-free input signal is assumed to be non gaussian, whereas the additive noises are assumed to be gaussian.

Indeed, it is first shown that fractional operator allows to derive in a straightforward way fractional models for thermal phenomena. In order to apply classical diagnosis methods, such models could be approximated by integer order models, but at the expense of much higher involved parameters and reduced precision. Thus, two diagnosis methods initially developed for integer order models are here extended to handle fractional order models. The first one is the generalized dynamic parity space method and the second one is the Luenberger diagnosis observer. Proposed methods are then applied to a single-input multi-output thermal testing bench and demonstrate the methods efficiency for detecting faults affecting thermal systems. © 2014 Elsevier B.V.},

Then, the commensurate order is estimated along with the differential equation coefficients using a non linear optimization technique combined to the ffocls algorithm (co-ffocls). Under some assumptions on the distributional properties of additive noises and the noise-free input signals, the developed estimators give consistent results. Hence, the noise-free input signal is assumed to be non gaussian, whereas the additive noises are assumed to be gaussian.

abstract = {Wireless Sensor Networks (WSN) can experience faults during deployment either due to its hardware malfunctioning or software failure or even harsh environmental factors. This results into presence of anomalies in their time-series collected data. So, these anomalies demand for reliable detection strategies to support in long term and/or in large scale WSN deployments. These data of physical variables are transmitted continuously to a repository for further processing of information as data stream. centralized fault detection based on centralized approach has become an emerging technology for building scalable and energy balanced applications for WSN. In our work, we try to implement the Distributed Fault Detection (DFD) algorithm in a central unit named SOFREL S550 which represent the base station or the sink node and detects the suspicious nodes by exchanging heartbeat messages in active manner. By analyzing the collected heartbeat information, the unit finally identifies failed nodes according to a pre-defined failure detection rule. © 2014 IEEE.},

Stability of the adaptive estimation is provided by a Lyapunov function ending with solving the Linear Matrix Inequalities (LMI). Therefore, thanks to the loop correction based on this novel estimation design, the process performances will be improved. As an example of simulation, a linear model describing an unicycle robot is proposed to illustrate the theoretical results. © 2014 IEEE.},

abstract = {Wireless Sensor Networks (WSNs) have been a significant system considerably exploited in numerous fields including medical, environmental, military and household applications. Yet, its high energy consumption and its potential fault vulnerability still their major drawback. Both of these issues require the implementation of fault distributed detection methods, capable of distinguishing faulty nodes from normal ones while minimizing energy. Thus, several approaches are proposed to detect these distributed errors, mentioning the Bayesian approach insuring the best choice of a proper sensor neighbourhood size n for best fault detection as well the energy conservation. In this paper, we define an energy minimization algorithm based on the Bayesian approach which ensures preventive sensor nodes pre-deployment against faults distribution. The Bayesian approach represents a study oscillating between Theory of Signal Detection (TSD), fault tolerance and energy minimization by determining the optimal parameters required to achieve this fault tolerance detection. This method includes the error probability due to the sensor itself which is included in the fault detection scheme thus the network will be more accurate. The experimental simulations will join a perceptive study allowing to the best choice of algorithm inputs then we will prouve that the proposed algorithm is able to provide a better detection performance while optimizing energy in WSN. © 2013 IEEE.},

First, the fault tolerant control strategy is designed based on Frobenius norm by minimizing the distance between the closed-loop model of the faulty system and a reference one. Therefore, stability issue is ensured via the Modified Pseudo-Inverse Method (MPIM). Finally, simulation tests on a two stage chemical reactor train with delay recycle streams illustrate the effectiveness of the proposed control approach. © 2013 West Pomeranian University of Technology.},

The proposed method allows the calculation of the gain matrix graphically through covering causal paths and loops based on the pole placement techniques for linear systems. The robust residuals are further generated from an uncertain bond graph model in linear fractional transformation (LFT) form so as to detect actuator faults in presence of parameter uncertainties. Simulation tests on a hydraulic system show the dynamic behavior of system variables and the robustness of the PI observers in the presence of modeling errors. The effectiveness of the proposed robust fault detection estimator is later illustrated via a DC motor.},

Thus, the qualitative approach (temporal causal graph) is invoved to isolate faults by using the progressive monitoring for the refinement of the various fault hypotheses.

In this paper, we define a faulttolerant and QoS based network layer for security management of chemical products warehouse which can be classified as real-time and mission critical application. This application generate routine data packets and alert packets caused by unusual events which need a high reliability, short end to end delay and low packet loss rate constraints. After each node compute his hop count and build his neighbors table in the initialization phase, packets can be routed to the sink. We use FELGossiping protocol for routine data packets and node-disjoint multipath routing protocol for alert packets. Furthermore, we utilize the information gathering phase of FELGossiping to update the neighbors table and detect the failed nodes, and we adapt the network topology changes by rerun the initialization phase when chemical units were added or removed from the warehouse. Analysis shows that the network layer is energy efficient and can meet the QoS constraints of unusual events packets.},

abstract = {The paper deals with the problems of robust stability for uncertain nonlinear polynomial systems. We consider the problem of the enlargement of the Robust Domain of Attraction (RDA). We propose a method to compute invariant subsets of the RDA for the asymptotically stable equilibrium point of polynomial systems. We use an optimization strategy based on Linear Matrix Inequality (LMI), to compute the RDA. The main contribution consists in a preliminary estimation of the general form of this region obtained by Trajectory Reversed Method (TRM) for all uncertain parameters. Moreover, an explicit determination of the RDA by using a parameterized Lyapunov Function is proposed. Such result is obtained by combined Threshold Accepting Algorithms (TAA) and LMI. An example is given to illustrate the efficiency of the proposed approach. © 2012 Praise Worthy Prize S.r.l. - All rights reserved.},

An integrated model for the combined dynamics of two interconnected subsystems is developed which provides an ideal frame work for the design of centralized and distributed FTC controllers. The additive FTC schemes obtained consist of an on-line estimation of faulty parameters for overall interconnected system and N-interconnected subsystems. Then, the estimated parameters are used to compute the feedback controller gains. The fault estimation and compensation is handled in this paper using the Singular Values Decomposition (SVD). Many strong points of the different architecture of FTC techniques are noted such as the possibility of making appropriate selection of control schemes based on specific representations (overall interconnected system/distributed N-subsystems coupling) of plant, as well as the facility of implementation by distributed processing FTC approach and some characteristics to realize improved performance of decentralized control.

This class of system contain N-interconnected subsystems. In fact, it operates one architecture for the direct adaptive method. This is a centralized feedback controller. It is assured by some adaptation laws which are proposed to estimate the unknown potential of sensors faults, disturbances and controller parameters Online. Then, a class of centralized controllers return state is constructed to automatically compensate for the effects of faults and external disturbances based on information extracted. An adaptive mechanism from a scheme where active fault tolerant system is exploited. The proposed techniques are finally evaluated in the light of a simulation for an overall interconnected system that can be decomposed into two subsystems coupling.},

The size of the scattering matrix of the total circuit depends only on the number of accessible modes in the beginning and the end of the overall structure. This feature makes the computation time of our hybrid method independent from distances between discontinuities of the circuit. The proposed hybrid method is successfully applied to the full-wave analysis of filters with great practical interest (i.e., multimode filters), thus improving computation time and memory storage against several full-wave finite element method based computer aided design tools. © 2011 IEEE.},

Indeed, the operating range of the process is partitioned into a set of operating regions. For each operation region a local model or/and controller is applied. The effective control applied to the process is a fusion of all these local control laws. In this paper, a multimodel H∞ Loop shaping controller (MM-HILSC) is designed and applied to a variably loaded DC motor. In order to use the system in variable load applications such as robot actuators, a multi-model controller is designed based on the H ∞ Loop shaping controllers (HILSC). Simulation results show a notable improvement relatively to the classical HILSC. The design controller is simplified by considering a reduced model obtained by decomposition of the global system into two time-scales singularly perturbed model of the DC motor. © 2011 IEEE.},

abstract = {This study presents a development of a global fuzzy control scheme for the vibration suppression and the input tracking of a flexible single-link manipulator based on fuzzy logic theory and commutation strategy. A flexible single-link with a horizontal planar vibration is considered and then the dynamic model is derived using Lagrange's equations and finite element method. To design the proposed global fuzzy controller, 2 separated mamdani fuzzy controllers are determined for the hub angle and the end-point residual loops. The control signal is the result of an auto-commutative takagi-sugeno fuzzy switcher that selects the adequate command to become the hub torque input. Simulation results of the global fuzzy controller are discussed in terms of level of vibration reduction, speed of response and trajectory tracking. © Medwell Journals, 2011.},

Finiteness conditions are established in terms of transfer function relative degree. Moreover, it is proven that the ℋ2-norm of a fractional transfer function with a proper integrator of order less than 0.5 may be finite.

abstract = {The composite state feedback control designed for singularly perturbed system SPS with small time-delay by using Lambert-W function is proposed in this paper. Based on the delayed slow subsystem (SS) and fast subsystems (FS) decomposition, we design a composite sate-feedback control. So the gain of delayed SS will be designed by using Lambert-W function and the gain of FS will be designed on the basis of classical pole placement method, and the two gains will be regrouped in global gain to design the delayed SPS. A numerical example is presented to illustrate the effectiveness of the proposed design approach.},

abstract = {This paper deals with the Permanent Magnet Synchronous Motor (PMSM) observability problems and proposes a simple and effective solution to improve the rotor speed and position estimation for Surface PMSM (SPMSM). In fact, the problem of loss of observability at low frequency range is always recognized in experimental settings. Nevertheless, there are no sufficient theoretical observability analyses for the PMSM. In the literature, only the sufficient observability condition has been presented. Therefore, the current work is aimed specially to the necessary observability condition analysis. In order to improve the rotor speed and position estimation in the case of SPMSM, a special attention is given to Model Reference Adaptive System (MRAS). MRAS based techniques are one of the best methods to estimate the rotor speed and position due to its performances and straight forward stability approach. In this paper, we propose a new robust MRAS scheme based on sliding mode techniques to estimate the rotor speed of a SPMSM. Furthermore, an Estimator/Observer swapping system is designed to overcome position observability problems at zero speed which is an unobservable state point. The stability of the proposed MRAS observer is also presented and discussed. Various tests are carried out in simulation using MATLAB/SIMULINK to illustrate the obtained theoretical results.},

Main attention is paid for the last one. The delay and the fault are integrated as a state variable. It is supposed that the delay and the fault are random variables. In addition, we provide some analytic results to demonstrate the computational advantages of two-stage Kalman filter over augmented ones. An example illustrates the obtained results is given. © 2010 IEEE.},

The aim of the study is to generate residual signals which, in the fault free case, are supposed to be identically zero. In practice, this condition is not satisfactory due to various factors such as measurements noise, model uncertainties, and more specifically the NCS communication induced delays. The effect of unknown networked induced delays on conventional observed residue generator is also studied in this paper. It is shown that the detection performances may be deteriorated because of the sensitivity of the residuals to the delays. The proposed approach is based on robust residual generation based on Kalman filtering. © 2010 Inderscience Enterprises Ltd.},

The stability of the proposed observer is also discussed. Various tests are carried out in simulation to highlight the effectiveness and the robustness of the proposed rotor speed and position estimations design.},

abstract = {In path planning, potential fields introduce force constraints to ensure curvature continuity of trajectories and thus to facilitate path-tracking design. In previous works, a path planning design by fractional (or generalized) repulsive potential has been developed to avoid fixed obstacles: danger level of each obstacle was characterized by the fractional order of differentiation, and a fractional road was determined by taking into account danger of each obstacle. If the obstacles are dynamic, the method was extended to obtain trajectories by considering repulsive and attractive potentials taking into account position and velocity of the robot with respect to obstacles. Then, a new attractive force based on fractional potential was developed. The advantage of the generalized normalized force is the possibility to control its variation. The curve is continuously varying and depends only on one parameter, the non integer order of the generalized attractive potential. But, in case of robot parameter variations, these two previous attractive forces do not allow to obtain robust path planning. A new fractional attractive force for robust path planning of mobile robot in dynamic environment was developed. In this paper, the robustness study in dynamic environment is presented. This method allows to obtain robust path planning despite robot mass variations. ©2009 IEEE.},

The Bond Graph model, used for supervision, incorporates the chemical kinetics of equilibrated reaction, heat and mass transport phenomena. Furthermore the causal and structural properties of the Bond Graph tool can be used to design FDI algorithms (i.e. the generation of fault indicators) to determine the availability of the chemical process. Structural analysis of the model is utilized to obtain the fault signatures for fault isolation. The diagnosis strategy is illustrated via a Continuous Stirred Tank Reactor (CSTR) example.},

We introduce the term of active security in the industrial chemical storage sector, taken in charge directly by the active product subjugated by a constrained security level. Petri Net modeling activity is conducted with the CPN-Tools software. We propose an Active product model and a human operator model and the associated cooperation mechanisms using ambient communication messaging. ©2009 IEEE.},

abstract = {The current problems to successfully apply sensorless control techniques for Permanent Magnet Synchronous Motor (PMSM) are the existence of operating conditions for which the observer performance is remarkably deteriorated. This is due to difficulties in estimating correctly the rotor position at low speed. The failure of sensor-less schemes in some particular operating conditions has been always recognized in experimental settings. However, there are no sufficient theoretical observability analysis for the PMSM. In the literature, only the sufficient observability condition has been presented. Therefore, the current work is aimed specially to necessary observability condition analysis. Thus, we give here the necessary and sufficient states observability condition for the PMSM. An example is presented to illustrate the results. © 2009 IEEE.},

abstract = {In this paper, a high performance speed control approach using artificial neural networks (ANNs) and Fuzzy Logic for the Field Oriented induction motor (IM) is proposed. This control method is developed using model reference adaptive control (MRAC) to improve the performance of the IM speed. By using an adaptive neural network controller (ANNC) in the MRAC method, the speed of an IM can be controlled to follow an arbitrarily selected speed trajectory. In particular, an accurate tracking of the speed can still be obtained when uncertainties in the motor and its load exists. The Fuzzy logic is used for the neural controller adaptation to improve the robustness of the generated command. In the proposed control scheme, the Model Reference Adaptive System (MRAS) is used to estimate the rotor speed and the rotor time constant parameter variation. The algorithm is verified by a series of computer simulations and the obtained results show that the designed control system can achieve satisfactory performances in the tracking to the speed trajectory and to the adaptability of the rotor time constant variation. © 2009 IEEE.},

Although rational orthogonal bases can be used to model any L2 [0, ∞ [ system, they fail to quickly capture the aperiodic multimode behavior with a limited number of terms.
