| 摘 要： | 根据非自治控制思想、异结构广义投影同步和Lyapunov稳定性定理,构造控制器使得2个异结构的混沌系统在短时间内实现同步,证明了混沌同步的稳定性,并将此同步系统应用到掩盖保密通信中。MATLAB数值仿真结果表明,该混沌系统能够实现稳定地同步,且在保密通信中,有用信号均能从接收端有效地恢复出来。

| Abstract: | A non-autonomous controller was designed based on non-autonomous control,generalized projective synchronization between two different configurations and Lyapunov stability theory,which realized two different chaotic systems globally synchronized.In this paper,the stability of the chaotic synchronization of two systems was verified,and the synchronized system was applied to the masking secure communication.Using the Matlab for numerical simulation,the results show that the method can realize synchronization ... |
