Synchronization of uncertain chaos system with time delay via hybrid feedback control

This paper investigates the synchronization of chaos system with external disturbance and time delay. Based on the Lyapunov stability theory and some inequality techniques, a simple hybrid feedback control method is designed to achieve synchronization between the master and slave systems. The controller can not only control the constant time delay systems, but also well control the time-varying delay systems. Numerical simulation is provided to illustrate the effectiveness of the proposed control method.
