摘要: 基于Lyapunov稳定性理论,采用主动控制思想研究了不同阶混沌系统广义投影同步问题,实现了混沌系统的广义投影同步,同时将该同步方法应用于保密通信中。数值仿真表明系统可实现广义投影同步,且在保密通信中能够有效恢复出有用信号。

Abstract: This paper is concerned with the generalized projective synchronization problem for two different order chaotic systems. Based on the Lyapunov stability theory, the generalized projective synchronization is achieved through active control method. The proposed method is also applied to secure communication. Numerical simulations are presented to demonstrate the method can realize generalized synchronization and the information signal can be recovered successfully in secure communication.

Key words: different order chaotic systems, generalized projective synchronization, secure communication, active control
