Abstract :
This paper introduces the chaos synchronization between two different hyperchaotic systems with fully unknown parameters, i. e. the synchronization between hyperchaotic Lorenz system and hyperchaotic Chen system. Based on the Lyapunov stability theory, an adaptive control law is derived for the case when the parameters of the drive and response systems to be synchronized are fully uncertain. Finally, numerical simulation results are presented to show the effectiveness of the techniques.
