Synchronization of uncertain Chen chaotic systems is discussed. Based on active control and virtual feedback control strategies, a novel active sliding mode controller is presented, which can ensure quick synchronization of uncertain chaos system starting from any initial condition. According to Lyapunov stable theory, the synchronization robust of uncertain chaos system is proved. A numerical simulation of uncertain Chen chaotic system is given to illustrate the effectiveness of the proposed strategies.
