Index. décimale : 621 Electronique Résumé : In this thesis, we considered the tracking control of a class of single-input single-output (SISO), and multi-input multi-output (MIMO) nonlinear uncertain systems, affine in control. We have proposed for a single-input single-output nonlinear systems three adaptive fuzzy control schemes, the first control scheme consist to approximate the feedback linearization law, by using the fuzzy system of Takagi-Sugeno type (direct approach) the second control scheme based on the approximation of the unknown nonlinear dynamics of the system, by using two fuzzy systems of Takagi-Sugeno type (indirect approach) in the third control scheme, we kept the structure of the second proposed scheme, but with the assumption that the sign of the control gain is unknown. For multi-input multi-output systems we have proposed an indirect adaptive fuzzy control scheme. The analysis of stability and robustness of the proposed control schemes are performed by using the Lyapunov synthesis method, and for each scheme, simulation results Diplôme : Magistère En ligne : ../theses/electronique/BOU6685.pdf Format de la ressource électronique : pdf Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=9937 Commande adaptative floue des systèmes non linéaires [texte imprimé] / Abdelhamid Bounemeur, Auteur ; Mohamed Chemachema, Directeur de thèse . - constantine (Route ain el bey, Algérie) : Université Constantine 1, 2014 . - 96 f. ; 30 cm. 2 copies imprimées disponibles Langues : Français (fre) Tags : Systèmes flous (Takagi-Sugeno)  Commande floue  Commande non linéaire  Commande adaptative  Systèmes non linéaires  Stabilité de Lyapunov  Gain de Nussbaum  Fuzzy systems (Takagi-Sugeno)  Fuzzy control  Nonlinear control  Adaptive control  Nonlinear systems  Lyapunov stability  Nussbaum Gain  ???? ???? )?????? ??????(  ?????? ??????  ?????? ??? ?????  ?????? ????????  ??????? ??? ??????  ??????? ????????  ????? ??? ??????

Contribution à la commande adaptative robuste d’une classe de systèmes non linéaires. / Nassira Zerari

Type de document : texte imprimé Auteurs : Nassira Zerari, Auteur ; Mohamed Chemachema, Auteur Editeur : Constantine : Université Mentouri Constantine Année de publication : 2019 Importance : 155 f.

The cases of the affine and non-affine systems, the presence of the constraints on the outputs and/or the states as well as the external perturbations are studied. Furthermore, the saturation and dead-zone inputs nonlinearities of the dynamical systems are investigated. In all the proposed approaches, the neural networks are used as universal approximators to estimate the unknown nonlinearities of the dynamical systems. The structures of the proposed controllers deal with the famous problems of explosion of complexity while avoiding the use of the traditional back-stepping technique. The proposed adaptive neural controllers have few online learning parameters compared to similar works. In addition, stability analysis of all control loops is carried out by using the Lyapunov method, and for each scheme, simulation results are given to show its effectiveness.
