18. Lyapunov exponent-based PID control for noisy chaotic systems

Author

Hamidouche, Baghdadi, Guesmi, Kamel, and Essounbouli, Najib

Abstract

This paper addresses the stabilisation issue of noisy chaotic systems. It proposes a new hybrid control approach that combines the proportional-integral-derivative (PID) method with the delayed feedback technique. The idea is to turn the structural stabilisation problem into an optimisation one. The goal is to determine the PIDgains that give the lowest value of the largest-Lyapunov exponent. The difference between the system's current state and its delayed value, by one period, is used as the PIDargument. As a result, the systems chaotic orbits are structurally stabilised to the greatest extent possible, the stable zone is extended, and the stabilisation time is reduced. Numerical simulations are carried out to show the effectiveness of the proposed approach on two well-known benchmarks of chaotic systems.

Abstract

This study provides an adaptive fuzzy control scheme for the class of nonlinear uncertain strict-feedback systems with external disturbances. The backstepping and synergetic control theories are used to develop a robust control approach for this class of systems. The unknown behaviors of the system are estimated through fuzzy systems. The stability is analyzed using the Lyapunov method, which shows that the proposed control method ensures that all the signals of the closed-loop system are bounded, and the tracking error converges approximately to zero. Two simulation examples are given to demonstrate the efficiency of the developed control approach. [ABSTRACT FROM AUTHOR]

Abstract

This work deals with the enhancement of Model Predictive Control approach when input constraints are imposed. We propose a two modified criteria to enhance the system dynamics and performances without need to relax the constraint on the control action. This objective is achieved by adding two objects in the classical criterion of control strategy: Maximization of the rate's change of the control action and energy minimization. The proposed technics are validated and applied to a cart with inverted pendulum system, their performances are evaluated through simulation results and a comparative study where results show the effectiveness of these one.

Abstract

This PhD manuscript deals with the modelling and control of DC-DC converters. We proposed enhancements on the modelling technique to combine the advantages of existing approaches while mitigating their disadvantages. We have shown that the improvements allow a more accurate description of the behavior of the converter behaviour without introducing simplifying assumptions or conditions of validity of the established model.Cncerning the control problem and in order to overcome the constraint of the choice of the operating point and to obtain a flexibility of the implementation of the controller, the fuzzy logic control has been adopted. In this context, two methods of synthesizing the fuzzy controller are developed. The first one is based on an analogy established between a fuzzy PID and the classical PID. This analogy has been used for the calculation of the fuzzy controller gains and their adjustment to achieve the regulation objectives.The idea of ​​the second approach, developed for the synthesis of the fuzzy controller, is to calculate analytically and in a systematic way the different parameters of the fuzzy controller guaranteeing the stability of the closed loop system with a desired dynamics. We focused first on period 1 operation in voltage-mode, then we showed that this approach can be extended to multi-period operation and current mode control. Thus the developed controller makes it possible to force the system to operate in period 1 and makes it possible to ensure the regulation performance while avoiding the appearance of the complex phenomena of the converter for a wide variation of the operating point and the parameters of the system. ., Notre travail porte sur la modélisation et la commande des convertisseurs statiques. Sur le volet modélisation nous avons proposé des améliorations permettant d’allier les avantages des approches existantes tout en atténuant leurs inconvénients. Nous avons montré que les améliorations apportées permettent une description plus fidèle du comportement du convertisseur sans introduire des hypothèses simplificatrices ou des conditions de validité. En ce qui concerne la commande des convertisseurs statiques et afin de s'affranchir de la contrainte du choix du point de fonctionnement et d’obtenir une flexibilité de la mise en œuvre du contrôleur, la commande par logique floue a été adoptée. Dans ce contexte, on à développer deux méthodes de synthèse du contrôleur flou. La première est basée sur une analogie établie entre un PID flou et le PID classique. Cette analogie a été exploitée pour le calcul des gains du contrôleur flou et leur ajustement pour atteindre les objectifs de régulation. L‘idée de la seconde approche, développée pour la synthèse du contrôleur flou, est de calculer analytiquement et d’une manière systématique les différents paramètres du contrôleur flou garantissant la stabilité du système bouclé avec une dynamique désirée. Nous nous sommes d’abord intéressés au fonctionnement en simple période (période 1) et à la commande en mode tension, et nous avons ensuite montré que cette approche peut être étendue au fonctionnement en périodes multiples et à la commande en mode courant, et que le contrôleur ainsi développé permet de forcer le système à fonctionner en période 1. Cette seconde approche permet d’assurer les performances de régulation tout en évitant l’apparition des phénomènes complexes du convertisseur pour une large variation du point de fonctionnement et des paramètres du système.
