对一类具有随机扰动的混沌系统同步的新方法

A New Approach of Synchronization to a Class of Chaotic System with Random Perturbation

本文基于工程上广为应用的状态观测器思想 ,在随机扰动存在的情况下 ,对一类非线性反馈混沌系统成功地实现了同步 .且在扰动很大时 ,系统仍能保持良好的同步性能 .最终的试验仿真结果也证明了这一点 。

In this paper,we realize successfully synchronization of chaotic system with nonlinear feedback when there exists random perturbation in the system,based on state observer.Even when the perturbation is very large,the chaotic system still synchronizes well,and the simulation results also verify it.So the results that we obtain are important to practical application.
