Abstract

Abstract: The exponential synchronization of Ikeda delayed chaotic systems is discussed. An exponential synchronization controller is designed based on Lyapunov stability theory and differential inequality. A sufficient condition of exponential synchronization is proposed by using the linear matrix inequality. The proposed method is applied to secure communications. Simulation shows that the proposed scheme has high speed and good robustness.
