Abstract

This paper investigates hybrid synchronization between two non-identical hyperchaotic systems using sliding mode control (SMC) strategy. Hyperchaotic Lu system is considered as master and hyperchaotic Bao system as slave system. The stability results are established using PI (Proportional Integral) switching surface and Lyapunov stability theory for hybrid synchronization scheme. SMC is used to reduce the influence of disturbance and improve system robustness which helps to achieve the convergence of error dynamics easily. Finally, numerical simulations are performed to demonstrate the effectiveness of proposed hybrid synchronization strategy of two non-identical hyperchaotic systems.
