Hybrid synchronization of hyperchaotic CAI systems via sliding mode control

Resumo

In this paper, we investigate the hybrid chaos synchronization of identical hyper-chaotic CAI systems by sliding mode control. In hybrid chaos synchronization of master and slave systems, the odd states of two systems are completely synchronized, while their even states are anti-synchronized. The stability results derived in this paper for hybrid chaos synchronization of identical hyper-chaotic CAI systems are established using Lyapunov stability. Since the Lyapunov exponents are not required for these calculations, the sliding mode control is very effective and convenient to achieve hybrid chaos synchronization of the identical hyper-chaotic CAI systems. Numerical simulations are shown to validate and demonstrate the effectiveness of the synchronization schemes derived in this paper.
