Synchronization of a class of chaotic systems in the presence of perturbation by an observer

Abstract

Synchronization problem in the presence of perturbation is considered,and the nolinear part of the chaotic system is nt in output feedback form.In this paper,we first transfer the system and obtain a nonfull order system.Second,we construct a synchronous system based on the nonlinear observer idea and realize the synchronization.Finally numerical example is illustrated and the simulation results verify the conclusion of this paper.
