The synchronization control of a uncertainty chaotic system

This paper deals with the robust synchronization control problem of continuous time scalar chaotic signals. It is based on the nonlinear state feedback linearization, optimal control and Lyapunov method. Under some certain assumptions, we obtained a simple controller with good performances. With the controller, chaotic system is global and asymptomatic synchronous. An application for the synchronization of a four-order autonomous chaotic system is presented.
