Robust Adaptive Synchronization of Hyperchaotic Chen and Lü Systems

This paper investigates the robust synchronization of uncertain hyper chaotic Chen and Lü systems. Based on Lyapunov stability theory and adaptive control, the adaptive robust controller is designed, which achieve synchronization of the two hyper chaotic systems with an arbitrarily small error by introducing a compensator. The update laws of the unknown parameters are given and the theoretical analysis is derived. Finally, numerical simulations are shown to verify the effectiveness and robustness of the proposed control scheme.
