abstract = {This work focuses on model-based fault diagnosis as well as fault-tolerant control of time-delayed Singularly Perturbed Systems (SPS) and Linear Parameter-Varying (LPV) with delay. 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.

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.

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.

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 

The main objective of this work is to describe the interference drawback in fourth 

generation mobile networks. The first section presents an interference analysis in the classic 

cellular networks named second and third generations is made. Simulations are carried out in 

urban environment while varying served users from 10 to 30 users. In a second section, we 

address the problem of interference in fourth generation mobile networks. In this context, two 

interference reduction techniques based on the frequency domain, time domain and that of power 

control are proposed. The last section will mainly show simulation results. The reader would 

be more satisfice over various experiments and essays that will consider main and various daily 

encountered situations.

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.},

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

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.

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},
