Chaos Synchronization of Systems via Accelerated Factors

Abstract

In this paper, chaos synchronization is investigated of a hyper-chaotic system with accelerated factors. An effectiveness controller is designed to realize the function projective synchronization for the hyper-chaotic system. Moreover, this paper improves the synchronization speed by adjusting accelerated factors. From the point of view of secure communication, more unpredictable factors can additionally enhance the security. Theory analysis and numerical simulations are presented to verify that the observer and controller are effective and feasible.
