Synchronization of a class of uncertain chaotic systems

Abstract

This paper presents an active control method for synchronization of two uncertain chaotic systems with parameters perturbation.A controller is designed to eliminate the nonlinear parts with the active control method.Based on Gerschgorin′s theorem in matrix theory,some simple generic criterions of global synchronization between two chaotic systems are established.To demonstrate the robustness and effectiveness of the proposed control strategy,it is applied to Lorenz systems and perfect simulation results are obtained.
