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.}, keywords = {Matrix converters;Entropy;Clustering algorithms;Uncertainty;Reliability;Weight measurement;Sparse matrices;Ensemble learning;Fuzzy systems;Spectral analysis;Fuzzy ensemble clustering;High-dimensional data;Random projection;Kullback-Leibler divergence entropy;Spectral learning}, pubstate = {published}, tppubtype = {article} } @article{Chakraborty2024241, title = {FC-SEEDA: fog computing-based secure and energy efficient data aggregation scheme for Internet of healthcare Things}, author = {Chinmay Chakraborty and Soufiene Ben Othman and Faris A.

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.}, keywords = {Uncertain systems;Backstepping;Adaptive systems;Uncertainty;Mechatronics;Conferences;Control systems;Nonlinear systems;adaptive control;Lyapunov;uncertain}, pubstate = {published}, tppubtype = {inproceedings} } @article{Jlidi2023, title = {An Artificial Neural Network for Solar Energy Prediction and Control Using Jaya-SMC}, author = {Mokhtar Jlidi and Fai\c{c}al Hamidi and Oscar Barambones and Rabeh Abbassi and Houssem Jerbi and Mohamed Aoun and Ali Karami-Mollaee}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85147810422\&doi=10.3390%2felectronics12030592\&partnerID=40\&md5=9a904af7a421f01ee1b834ef748dcce0}, doi = {10.3390/electronics12030592}, year = {2023}, date = {2023-01-01}, journal = {Electronics (Switzerland)}, volume = {12}, number = {3}, 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.}, note = {Cited by: 2; All Open Access, Gold Open Access, Green Open Access}, keywords = {}, pubstate = {published}, tppubtype = {article} } @article{Chetoui20231868, title = {Fourth-order cumulants based-least squares methods for fractional Multiple-Input-Single-Output Errors-In-Variables system identification}, author = {Manel Chetoui and Mohamed Aoun}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85162025508\&doi=10.1007%2fs13540-023-00174-z\&partnerID=40\&md5=e432a1b99e5eefa5d83aa9d25a97537f}, doi = {10.1007/s13540-023-00174-z}, year = {2023}, date = {2023-01-01}, journal = {Fractional Calculus and Applied Analysis}, volume = {26}, number = {4}, pages = {1868 \textendash 1893}, 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.}, note = {Cited by: 0}, keywords = {}, pubstate = {published}, tppubtype = {article} } @conference{Ethabet2023, title = {L∞ Set-membership Estimation for Continuous-time Switched Linear Systems}, author = {Haifa Ethabet and Leila Dadi and Tarek Raissi and Mohamed Aoun}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85182931405\&doi=10.1109%2fIW_MSS59200.2023.10369668\&partnerID=40\&md5=2fb780affae1b8628f3f526c9cabfef7}, doi = {10.1109/IW_MSS59200.2023.10369668}, year = {2023}, date = {2023-01-01}, journal = {2023 IEEE International Workshop on Mechatronics Systems Supervision, IW_MSS 2023}, abstract = {In this work, we focuses on the problem of designing an interval state estimation for continuous-time Switched Linear Systems (SLS) in the Unknown But Bounded Error (UBBE) context.

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 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.}, keywords = {Autonomous switching sequence, Hybrid switched systems, Hybrid switching systems, Hybrid systems, Identification problem, Numerical methods, Optimization techniques, Particle swarm, Particle swarm optimization, Particle swarm optimization (PSO), Swarm optimization, Switching instants, Switching sequence}, pubstate = {published}, tppubtype = {conference} } @conference{Saada2023, title = {Examining DIDIM and IV Approaches through the Double Least Squares Method for Comparative Assessment}, author = {Fadwa Saada and Karim Chabir and Mohamed Naceur Abdelkrim}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85182941796\&doi=10.1109%2fIW_MSS59200.2023.10369269\&partnerID=40\&md5=3b2e0c922b926ee775dfe3a963844772}, doi = {10.1109/IW_MSS59200.2023.10369269}, year = {2023}, date = {2023-01-01}, journal = {2023 IEEE International Workshop on Mechatronics Systems Supervision, IW_MSS 2023}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @conference{Sakl20231142, title = {DL Methods for Skin Lesions Automated Diagnosis In Smartphone Images}, author = {Marwen Sakl and Chaker Essid and Bassem Ben Salah and Hedi Sakli}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85167710093\&doi=10.1109%2fIWCMC58020.2023.10183254\&partnerID=40\&md5=114719a149be9621210ab8022b8b21ed}, doi = {10.1109/IWCMC58020.2023.10183254}, year = {2023}, date = {2023-01-01}, journal = {2023 International Wireless Communications and Mobile Computing, IWCMC 2023}, pages = {1142 \textendash 1147}, note = {Cited by: 0}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @conference{HadjSalem2023, title = {Simulation of an Energy Management System and Control in a Multi-Source System}, author = {Mariem Hadj Salem and Karim Mansouri and Eric Cauveau and Yemna Bensalem and Mohamed Naceur Abdelkrim}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85182917541\&doi=10.1109%2fIW_MSS59200.2023.10368935\&partnerID=40\&md5=147cd5876aa69b5aac36691ce4a8276e}, doi = {10.1109/IW_MSS59200.2023.10368935}, year = {2023}, date = {2023-01-01}, journal = {2023 IEEE International Workshop on Mechatronics Systems Supervision, IW_MSS 2023}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @book{Ghabri2023103, title = {Artificial intelligence used to recognize fetal planes based on ultrasound scans during pregnancy}, author = {Haifa Ghabri and Ben Othman Soufiene and Hedi Sakli}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85177059064\&doi=10.1201%2f9781003366249-7\&partnerID=40\&md5=5c83d6ea0a23768caaaf597345d278ad}, doi = {10.1201/9781003366249-7}, year = {2023}, date = {2023-01-01}, journal = {Machine Learning and Deep Learning Techniques for Medical Image Recognition}, pages = {103 \textendash 114}, note = {Cited by: 0}, keywords = {}, pubstate = {published}, tppubtype = {book} } @conference{Benjemaa2023, title = {State feedback control for LPV neutral time delay descriptor systems}, author = {Rabeb Benjemaa and Aicha Elhsoumi and Mohamed Naceur Abdelkrim}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85182928110\&doi=10.1109%2fIW_MSS59200.2023.10369343\&partnerID=40\&md5=a2e529e1caf90174007d9e29e5c7536a}, doi = {10.1109/IW_MSS59200.2023.10369343}, year = {2023}, date = {2023-01-01}, journal = {2023 IEEE International Workshop on Mechatronics Systems Supervision, IW_MSS 2023}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @conference{Mhamdi2023, title = {A Brief Overview of Blockchain Technology and Access Control in IoT}, author = {Halima Mhamdi and Ahmed Zouinkhi and Mohamed Naceur Abdelkrim}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85182931642\&doi=10.1109%2fIW_MSS59200.2023.10369788\&partnerID=40\&md5=84147ee67dd8fe576c7ea7ecac0adc04}, doi = {10.1109/IW_MSS59200.2023.10369788}, year = {2023}, date = {2023-01-01}, journal = {2023 IEEE International Workshop on Mechatronics Systems Supervision, IW_MSS 2023}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @conference{Sakli2023, title = {Deep Learning-Based Multi-Stage Analysis for Accurate Skin Cancer Diagnosis using a Lightweight CNN Architecture}, author = {Marwen Sakli and Chaker Essid and Bassem Ben Salah and Hedi Sakli}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85179555438\&doi=10.1109%2fINISTA59065.2023.10310615\&partnerID=40\&md5=8e0012f4b06db07df0bb207524b2b3b4}, doi = {10.1109/INISTA59065.2023.10310615}, year = {2023}, date = {2023-01-01}, journal = {17th International Conference on INnovations in Intelligent SysTems and Applications, INISTA 2023 -

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.}, note = {Cited by: 2; All Open Access, Gold Open Access, Green Open Access}, keywords = {}, pubstate = {published}, tppubtype = {article} } @article{Chetoui20231868b, title = {Fourth-order cumulants based-least squares methods for fractional Multiple-Input-Single-Output Errors-In-Variables system identification}, author = {Manel Chetoui and Mohamed Aoun}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85162025508\&doi=10.1007%2fs13540-023-00174-z\&partnerID=40\&md5=e432a1b99e5eefa5d83aa9d25a97537f}, doi = {10.1007/s13540-023-00174-z}, year = {2023}, date = {2023-01-01}, journal = {Fractional Calculus and Applied Analysis}, volume = {26}, number = {4}, pages = {1868 \textendash 1893}, 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.}, note = {Cited by: 0}, keywords = {}, pubstate = {published}, tppubtype = {article} } @conference{Ethabet2023b, title = {L∞ Set-membership Estimation for Continuous-time Switched Linear Systems}, author = {Haifa Ethabet and Leila Dadi and Tarek Raissi and Mohamed Aoun}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85182931405\&doi=10.1109%2fIW_MSS59200.2023.10369668\&partnerID=40\&md5=2fb780affae1b8628f3f526c9cabfef7}, doi = {10.1109/IW_MSS59200.2023.10369668}, year = {2023}, date = {2023-01-01}, journal = {2023 IEEE International Workshop on Mechatronics Systems Supervision, IW_MSS 2023}, abstract = {In this work, we focuses on the problem of designing an interval state estimation for continuous-time Switched Linear Systems (SLS) in the Unknown But Bounded Error (UBBE) context. 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.

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.

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.

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}, note = {Cited by: 10}, keywords = {Continous time, Continuous time systems, Fractional model, Fractional systems, Instrumental variables, Intelligent systems, Monte Carlo methods, Multiple input single output systems, Multiple inputs single outputs, Optimization, Optimization algorithms, Order estimation, Order optimizations, Parameter estimation, Religious buildings, System-identification}, pubstate = {published}, tppubtype = {article} } @conference{Akremi2022265, title = {L∞/H∞Functional Interval Observers Design for Multivariable Systems}, author = {Rihab Akremi and Rihab Lamouchi and Messaoud Amairi}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85136302914\&doi=10.1109%2fMED54222.2022.9837179\&partnerID=40\&md5=915f3b2c51188cd1014295a3032bb0d7}, doi = {10.1109/MED54222.2022.9837179}, year = {2022}, date = {2022-01-01}, journal = {2022 30th Mediterranean Conference on Control and Automation, MED 2022}, pages = {265 \textendash 270}, note = {Cited by: 0}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @article{Yakoub2022, title = {A Bias-Corrected Method for Fractional Linear Parameter Varying Systems}, author = {Zaineb Yakoub and Omar Naifar and Messaoud Amairi and Manel Chetoui and Mohamed Aoun and Abdellatif Ben Makhlouf}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85128182629\&doi=10.1155%2f2022%2f7278157\&partnerID=40\&md5=6ea775beb03cf2de78d054b3e4819d41}, doi = {10.1155/2022/7278157}, year = {2022}, date = {2022-01-01}, journal = {Mathematical Problems in Engineering}, volume = {2022}, abstract = {This paper proposes an identification algorithm for the fractional Linear Parameter Varying (LPV) system considering noisy scheduling and output measurements.

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

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}, note = {Cited by: 10}, keywords = {Continous time, Continuous time systems, Fractional model, Fractional systems, Instrumental variables, Intelligent systems, Monte Carlo methods, Multiple input single output systems, Multiple inputs single outputs, Optimization, Optimization algorithms, Order estimation, Order optimizations, Parameter estimation, Religious buildings, System-identification}, pubstate = {published}, tppubtype = {article} } @article{Yakoub2022e, title = {A Bias-Corrected Method for Fractional Linear Parameter Varying Systems}, author = {Zaineb Yakoub and Omar Naifar and Messaoud Amairi and Manel Chetoui and Mohamed Aoun and Abdellatif Ben Makhlouf}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85128182629\&doi=10.1155%2f2022%2f7278157\&partnerID=40\&md5=6ea775beb03cf2de78d054b3e4819d41}, doi = {10.1155/2022/7278157}, year = {2022}, date = {2022-01-01}, journal = {Mathematical Problems in Engineering}, volume = {2022}, abstract = {This paper proposes an identification algorithm for the fractional Linear Parameter Varying (LPV) system considering noisy scheduling and output measurements.

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.

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.

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.}, keywords = {Location awareness;Histograms;Pipelines;Distribution networks;Tools;Soil;Thermal analysis;Sustainable development goals (SDG);non-destructive evaluation (NDE);infrared thermography;water leak detection;multitemporal analysis}, pubstate = {published}, tppubtype = {article} } @article{9393558, title = {Polarimetric SAR Image Filtering by Infinite Number of Looks Prediction Technique}, author = {Mohamed Yahia and Tarig Ali and Md.

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.

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.}, note = {Cited by: 9}, keywords = {}, pubstate = {published}, tppubtype = {article} } @conference{Baccouche2021, title = {Energy harvesting by optical rectenna for RFID and IoT applications}, author = {Chokri Baccouche and Chayma Bahhar and Hedi Sakli}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85125964319\&partnerID=40\&md5=a0c2b1c20b14618bc66229cf140c0010}, year = {2021}, date = {2021-01-01}, journal = {2021 29th International Conference on Software, Telecommunications and Computer Networks, SoftCOM 2021}, note = {Cited by: 1}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @article{Chairet20211245b, title = {Potential of Multi-scale Completed Local Binary Pattern for Object Based Classification of Very High Spatial Resolution Imagery}, author = {Radhia Chairet and Yassine Ben Salem and Mohamed Aoun}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85100741972\&doi=10.1007%2fs12524-021-01311-y\&partnerID=40\&md5=c98864af43bd0c312cd2cdd3e4bffe10}, doi = {10.1007/s12524-021-01311-y}, year = {2021}, date = {2021-01-01}, journal = {Journal of the Indian Society of Remote Sensing}, volume = {49}, number = {6}, pages = {1245 \textendash 1255}, abstract = {This paper explores the potentiality of using the completed local binary pattern (CLBP) for the classification of an urbanized oasis area situated in southeastern Tunisia, in very high spatial resolution GeoEye imagery. 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.}, note = {Cited by: 5}, keywords = {classification, GeoEye, mapping method, NDVI, satellite imagery, spatial resolution, supervised classification, Tunisia, urban area}, pubstate = {published}, tppubtype = {article} } @article{Souid2021, title = {Classification and predictions of lung diseases from chest x‐ rays using mobilenet v2}, author = {Abdelbaki Souid and Nizar Sakli and Hedi Sakli}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85103475543\&doi=10.3390%2fapp11062751\&partnerID=40\&md5=bab58a283babc38644b403e9f5e0098e}, doi = {10.3390/app11062751}, year = {2021}, date = {2021-01-01}, journal = {Applied Sciences (Switzerland)}, volume = {11}, number = {6}, note = {Cited by: 55; All Open Access, Gold Open Access}, keywords = {}, pubstate = {published}, tppubtype = {article} } @article{Sakli202138546, title = {Metamaterial-Based Antenna Performance Enhancement for MIMO System Applications}, author = {Hedi Sakli and C.

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.

Next, new fuzzy cluster validity index (VI) is applied to evaluate the accurate number of the selected clusters.

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.

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.}, keywords = {Speckle;Synthetic aperture radar;Optical filters;Information filters;Filtering algorithms;Iterative minimum mean square error (IMMSE) filter;nonlocal means filter;synthetic aperture radar (SAR);speckle}, pubstate = {published}, tppubtype = {article} } @article{Atitallah2020128, title = {Diagnosis of time-delay fractional systems using observer-based methods}, author = {Halima Atitallah and Asma Aribi and Mohamed Aoun}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85082651176\&doi=10.1504%2fIJDSDE.2020.106028\&partnerID=40\&md5=65e5911ee7fb678504ed4979565642ee}, doi = {10.1504/IJDSDE.2020.106028}, year = {2020}, date = {2020-01-01}, journal = {International Journal of Dynamical Systems and Differential Equations}, volume = {10}, number = {2}, pages = {128 \textendash 148}, abstract = {In this paper, two model-based methods are considered for the diagnosis of time-delay fractional systems.

A theoretical study investigating the convergence condition for each observer-based method in terms of matrix inequalities is presented. Residual sensitivities to faults and to disturbances are studied. Time-delay fractional unknown input observer parameters are computed to obtain structured residuals. This observer ensures unknown input decoupling from the state which results residual insensitive to unknown inputs.

The contribution of system whole past to future output is taken into account as an initialization function. Provided the initialization function is upper and lower bounded, it is shown in this paper that the fractional interval observer (FIO) allows to bound pseudo-state free responses by an upper and a lower trajectory. 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. Finally, a numerical example is given to show the effectiveness of the proposed methods on the initialization of fractional linear systems. © 2019 Elsevier B.V.}, note = {Cited by: 6; All Open Access, Bronze Open Access, Green Open Access}, keywords = {A-stable, Additive noise, Estimation errors, Fractional systems, Free response, Initialization, Interval observers, Linear systems, Non negatives, Numerical methods, Pseudo state}, pubstate = {published}, tppubtype = {article} } @conference{Neji2020338, title = {T-LEACH: Threshold sensitive Low Energy Adaptive Clustering Hierarchy for Wireless Sensor Networks}, author = {Wafa Neji and Soufiene Ben Othman and Hedi Sakli}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85100495167\&doi=10.1109%2fSTA50679.2020.9329354\&partnerID=40\&md5=96bba821dfd0387f4eaea822a7b09a92}, doi = {10.1109/STA50679.2020.9329354}, year = {2020}, date = {2020-01-01}, journal = {Proceedings - STA 2020: 2020 20th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering}, pages = {338 \textendash 342}, note = {Cited by: 4}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @article{BenSalem20204390, title = {Texture classification of fabric defects using machine learning}, author = {Yassine Ben Salem and Mohamed Naceur Abdelkrim}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85083102520\&doi=10.11591%2fijece.v10i4.pp4390-4399\&partnerID=40\&md5=cb4b26ac6c30ba9f2d9174c477530f36}, doi = {10.11591/ijece.v10i4.pp4390-4399}, year = {2020}, date = {2020-01-01}, journal = {International Journal of Electrical and Computer Engineering}, volume = {10}, number = {4}, pages = {4390 \textendash 4399}, note = {Cited by: 8; All Open Access, Gold Open Access, Green Open Access}, keywords = {}, pubstate = {published}, tppubtype = {article} } @conference{Fitouri2020681, title = {Comparison between 2D and 3D Modeling of Permanent Magnet Synchronous Motor Using FEM Simulations}, author = {Manel Fitouri and Yemna Bensalem and Mohamed Naceur Abdelkrim}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85103023630\&doi=10.1109%2fSSD49366.2020.9364256\&partnerID=40\&md5=7cd402de3276c3c9e5d2aeb4986d9cd1}, doi = {10.1109/SSD49366.2020.9364256}, year = {2020}, date = {2020-01-01}, journal = {Proceedings of the 17th International Multi-Conference on Systems, Signals and Devices, SSD 2020}, pages = {681 \textendash 685}, note = {Cited by: 4}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @conference{Kilani2020343, title = {Social behaviorism model for interactions management in Industrial IoT}, author = {Rim Kilani and Ahmed Zouinkhi and Eddy Bajic and Mohamed Naceur Abdelkrim}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85103028760\&doi=10.1109%2fSSD49366.2020.9364096\&partnerID=40\&md5=eb6ac59a065fb85f1fe7df789c061e68}, doi = {10.1109/SSD49366.2020.9364096}, year = {2020}, date = {2020-01-01}, journal = {Proceedings of the 17th International Multi-Conference on Systems, Signals and Devices, SSD 2020}, pages = {343 \textendash 348}, note = {Cited by: 1}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @conference{Ethabet2020279b, title = {Fault Detection and Isolation for Continuous-Time Switched Linear Systems: A Set Membership Approach}, author = {Haifa Ethabet and Tarek Raissi and Messaoud Amairi and Mohamed Aoun}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85103019738\&doi=10.1109%2fSSD49366.2020.9364097\&partnerID=40\&md5=e2297b397f94ac2755b2faf5d9e3ab2e}, doi = {10.1109/SSD49366.2020.9364097}, year = {2020}, date = {2020-01-01}, journal = {Proceedings of the 17th International Multi-Conference on Systems, Signals and Devices, SSD 2020}, pages = {279 \textendash 284}, abstract = {In this paper, the problem of Fault Detection and Isolation (FDI) is investigated for continuous-Time switched linear systems via a set-membership approach.

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 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.

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.

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.

Then, high performances are shown through real time implementation using the ARDUINO MEGA 2560 device. © 2018, Institute of Automation, Chinese Academy of Sciences and Springer-Verlag GmbH Germany, part of Springer Nature.}, note = {Cited by: 0}, keywords = {Arduino, Asymptotic stability, Degrees of freedom (mechanics), Digital control systems, Discrete - time systems, Discrete time control systems, Linear matrix inequalities, Lipschitz systems, Performance analysis, Real time control, Reduced order observers}, pubstate = {published}, tppubtype = {article} } @article{Ettouil2019555, title = {Synergetic Control for HVAC System Control and VAV Box Fault Compensation}, author = {Radhia Ettouil and Karim Chabir and Dominique Sauter and Mohamed Naceur Abdelkrim}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85073193484\&doi=10.2478%2famcs-2019-0041\&partnerID=40\&md5=a52441b3d8b54002d4b274c201c492fd}, doi = {10.2478/amcs-2019-0041}, year = {2019}, date = {2019-01-01}, journal = {International Journal of Applied Mathematics and Computer Science}, volume = {29}, number = {3}, pages = {555 \textendash 570}, note = {Cited by: 1; All Open Access, Gold Open Access}, keywords = {}, pubstate = {published}, tppubtype = {article} } @conference{Griba2019262, title = {Synchronization of Chaotic Systems: A survey study}, author = {Noussaiba Griba and Faical Hamidi and Kamel Menighed and Boumedyen Boussaid and Mohamed Naceur Abdelkrim}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85089558899\&doi=10.1109%2fSCC47175.2019.9116133\&partnerID=40\&md5=20ddb79b75bd84f2b1f8aa970dd3cca2}, doi = {10.1109/SCC47175.2019.9116133}, year = {2019}, date = {2019-01-01}, journal = {2019 International Conference on Signal, Control and Communication, SCC 2019}, pages = {262 \textendash 267}, note = {Cited by: 2}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @article{Yakoub20192909, title = {On the fractional closed-loop linear parameter varying system identification under noise corrupted scheduling and output signal measurements}, author = {Zaineb Yakoub and Messaoud Amairi and Mohamed Aoun and Manel Chetoui}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85061267074\&doi=10.1177%2f0142331218821409\&partnerID=40\&md5=74b33d7ecf26b354ee27592a193b26d9}, doi = {10.1177/0142331218821409}, year = {2019}, date = {2019-01-01}, journal = {Transactions of the Institute of Measurement and Control}, volume = {41}, number = {10}, pages = {2909 \textendash 2921}, 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 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.

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.

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.

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.

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.

In the case of a fractional commensurate system, an iterative algorithm is proposed to deal with commensurate-order estimation. The performances of the proposed algorithm are illustrated by a numerical example via a Monte Carlo simulation. © The Author(s) 2018.}, note = {Cited by: 5}, keywords = {}, pubstate = {published}, tppubtype = {article} } @conference{Mansour2018381, title = {Mobile robot localization based on interval analysis and mobile beacons}, author = {Fatma Mansour and Messaoud Amairi and Mohamed Naceur Abdelkrim}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85050031432\&doi=10.1109%2fASET.2018.8379886\&partnerID=40\&md5=094e81a2cdad70f294b9e6cddd900827}, doi = {10.1109/ASET.2018.8379886}, year = {2018}, date = {2018-01-01}, journal = {2018 International Conference on Advanced Systems and Electric Technologies, IC_ASET 2018}, pages = {381 \textendash 386}, note = {Cited by: 1}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @conference{Gasmi2018111, title = {H ∞ Sliding Window Observer Design for Lipschitz Discrete-Time Systems}, author = {Noussaiba Gasmi and Mohamed Boutayeb and Assem Thabet and Mohamed Aoun}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85061079973\&doi=10.1109%2fICoSC.2018.8587622\&partnerID=40\&md5=35bde69fee7112543b44587ab1dda799}, doi = {10.1109/ICoSC.2018.8587622}, year = {2018}, date = {2018-01-01}, journal = {2018 7th International Conference on Systems and Control, ICSC 2018}, pages = {111 \textendash 116}, abstract = {This paper focuses on the H ∞ observer design for Lipschitz discrete-time nonlinear systems.

Abstract The energy consumption in wireless sensor networks presents a serious problem. Our study is dedicated entirely to the IEEE 802.15.4 standard. We have proposed a mathematical model of energy consumption. In order to optimize energy consumption in this standard, we have developed duty cycle adjustment algorithms according to the energy level remaining in the battery of a node for both modes (beacon mode and non beacon mode). The algorithms proposed for the first mode make it possible to manipulate the parameters BO and SO of standard IEEE 802.15.4 in order to adjust the energy consumption according to the residual energy. For the second mode (non textit beacon mode), the duty cycle was managed according to the remaining energy level. INETMANET / Omnet ++ simulator is used to evaluate the performances of the proposed algorithms. Then, a practical validation was executed with the real platform of wireless sensor network of kind TeensyWino .

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.

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}, note = {Cited by: 8}, keywords = {Control nonlinearities, Controller designs, Controllers, Decoding, Delayed state, Digital control systems, Discrete - time systems, Discrete time control systems, Linear matrix inequalities, Linear matrix inequality approach, Lipschitz systems, Noise analyse, Observer-based controller design, Observer-based controllers, Robustness (control systems), Sliding Window, Sliding window of measurement}, pubstate = {published}, tppubtype = {article} } @conference{Bougatef2018146, title = {UIO Design and sensor fault diagnosis of LPV systems with time delay using descriptor approach}, author = {Zina Bougatef and Nouceyba Abdelkrim and Abdelouhab Aitouche and Mohamed Naceur Abdelkrim}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85060616508\&doi=10.1109%2fSSD.2018.8570436\&partnerID=40\&md5=79ddaa06c67bad7e5b8c12e675e6bb07}, doi = {10.1109/SSD.2018.8570436}, year = {2018}, date = {2018-01-01}, journal = {2018 15th International Multi-Conference on Systems, Signals and Devices, SSD 2018}, pages = {146 \textendash 150}, note = {Cited by: 4}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @conference{Bougatef201886, title = {Fault diagnosis and accommodation for singularly perturbed time-delayed systems: Descriptor approach}, author = {Zina Bougatef and Nouceyba Abdelkrim and Adel Tellili and Mohamed Naceur Abdelkrim}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85048437679\&doi=10.1109%2fSTA.2017.8314865\&partnerID=40\&md5=7b90cf3ee062d1bee3a6885819f765bb}, doi = {10.1109/STA.2017.8314865}, year = {2018}, date = {2018-01-01}, journal = {2017 18th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering, STA 2017 - Proceedings}, volume = {2018-January}, pages = {86 \textendash 92}, note = {Cited by: 4}, keywords = {}, pubstate = {published}, tppubtype = {conference} } @conference{Achnib2018863b, title = {Anticipative Robust Design Applied to a Water Level Control System}, author = {Asma Achnib and Tudor-Bogdan Airimitoaie and Patrick Lanusse and Ayadi Guefrachi and Mohamed Aoun and Manel Chetoui}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85057100557\&doi=10.23919%2fECC.2018.8550606\&partnerID=40\&md5=c3634547027f49e719b9a1021df8b6ae}, doi = {10.23919/ECC.2018.8550606}, year = {2018}, date = {2018-01-01}, journal = {2018 European Control Conference, ECC 2018}, pages = {863 \textendash 869}, abstract = {In this paper, a discrete-time robust controller design method for optimal reference tracking in preview systems is validated on an experimental test bench.

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.

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 Keywords: Large Scale Systems, Non linear interconnected system, Observer based decentralized control, Differential Mean Value Theorem, LMI optimization, Lyapunoc Stability, Robust control, H1 filtering}, keywords = {Th\`{e}se}, pubstate = {published}, tppubtype = {phdthesis} } @phdthesis{LAMOUCHI2017, title = {Contributions \`{a} l’observation et \`{a} la commande tol\'{e}rante aux fautes des syst\`{e}mes incertains}, author = {Rihab LAMOUCHI}, url = {https://tel.archives-ouvertes.fr/tel-01683146 https://macs.tn/macs/wp-content/uploads/2018/11/These_Riheb_lammouchi-717x1024.png https://macs.tn/macs/wp-content/uploads/2018/11/Slide1-1024x709.jpg https://macs.tn/macs/wp-content/uploads/2018/11/These_Riheb_lammouchi-717x1024.png}, year = {2017}, date = {2017-01-01}, school = {ENIG-CNAM Paris}, abstract = {R\'{e}sum\'{e} 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.

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.

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.

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.

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.

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.

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.

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. Hence, fractional orthogonal bases are expected to better approximate fractional models with fewer parameters. Intuitive reasoning could lead to simply extending the differentiation order of existing bases from integer to any positive real number. However, classical Laguerre, and by extension Kautz and generalized orthogonal basis functions, are divergent as soon as their differentiation order is non-integer. In this paper, the first fractional orthogonal basis is synthesized, extrapolating the definition of Laguerre functions to any fractional order derivative. Completeness of the new basis is demonstrated. Hence, a new class of fixed denominator models is provided for fractional system approximation and identification. © 2007 Elsevier Ltd.

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. Hence, fractional orthogonal bases are expected to better approximate fractional models with fewer parameters. Intuitive reasoning could lead to simply extending the differentiation order of existing bases from integer to any positive real number. However, classical Laguerre, and by extension Kautz and generalized orthogonal basis functions, are divergent as soon as their differentiation order is non-integer. In this paper, the first fractional orthogonal basis is synthesized, extrapolating the definition of Laguerre functions to any fractional order derivative. Completeness of the new basis is demonstrated. Hence, a new class of fixed denominator models is provided for fractional system approximation and identification. © 2007 Elsevier Ltd.
