Résumé:
Chaos theory deals with deterministic dynamical systems. In this work, a
description of the main characteristics of chaotic dynamical systems followed by the
study of two hyperjerk chaotic systems. Synchronization of two identical systems by
three control methods is performed. Next, a synchronization of two systems using a
sliding mode observer is proposed. Simulation under Matlab / Simulink was performed
to analyze their performance. Finally, a system implementation and its sliding-mode
هobserver are carried out. The comparison of the obtained results showed good
agreement
