基于反馈的混沌同步及其应用

Chaos Synchronization and Its Application Based on Feedback

针对参数确定的Rikitake混沌系统的同步控制和在保密通信中的应用进行设计、证明和仿真研究,采用单变量线性状态反馈同步方法,设计出一种线性反馈控制器,并利用拉普拉斯变换原理及终值定理证明该控制器的有效性,能够实现性能良好的混沌同步,进而运用混沌掩盖的方法将该同步方法应用于保密通信,数值模拟进一步证明该控制器的有效性。

Rikitake parameters for determining the chaotic system of simultaneous control and confidentiality of communications in the application of the design,certification and simulation.Uses a single-state feedback synchronous linear variable methods,designs a linear feedback controller,and uses Laplace transformation principle and final theorem to prove the validity of the controller,and achieves good performance of synchronization,then Chaos cover up the use of the method of simultaneous method has been applied to confidential communications,and the numerical simulation further proves the effectiveness of the controller.
