In this paper, design of SMC based controller is proposed for anti synchronization of hyper chaotic 4D Lu systems. To achieve this goal, using the sliding mode control scheme and Lyapunov stability theory, a proportional integral (PI) switching surface is proposed to ensure the stability of the closed-loop error system in sliding motion. Having established the PI switching surface, a sliding mode controller is designed. This controller is effective and guarantees the occurrence of sliding motion and achieves anti-synchronization of master slave hyper chaotic Lu system. Finally, numerical simulations are performed to demonstrate the effectiveness of the proposed control strategy.
