Abstract:
In this paper the synchronization problem of two identical Chen chaotic systems is studied and the design of a sliding mode synchronization control method of Chen chaotic system. This paper directly makes master-slave Chen chaoic system satisfy stability in the Lyapunov sense, and desighs the sliding mode controller. Moreover, the information signal can be recovered undistorted when this method is applied to secure communication. Experimental results show that this method has good robustness and safety.
Key words:

摘要: 设计一种滑模控制器,用于实现2个相同Chen混沌系统的同步。根据主从Chen混沌系统满足Lyapunov稳定性理论的条件,设计滑模控制器,使用混沌掩盖的方法将其应用于保密通信中,以掩盖和无失真地恢复有用信号。实验结果表明,该方法具有较好的鲁棒性和较高的安全性。
