Sur la synchronisation des systèmes chaotiques à temps discret

Abstract

In this thesis, some problems regarding the synchronization of chaotic systems in discrete-time are studied. Based on Lyapunov theory and nonlinear control methods, new synchronization criterions in discrete-time chaotic systems are derived. In addition, several types of generalized synchronization are developed such as inverse generalized synchronization and φ –Λ synchronization generalized. Numerical simulations are used to validate the proposed results.
