离散混沌系统同步的一类反馈控制方法

A Class of Feedback Control Methods for Synchronization of Discrete Chaotic System

近年来，混沌的控制与同步在通信中的应用前景受到人们的广泛关注。本文提出了一类基于反馈控制的混沌同步化方法，这些方法以误差反馈为基础，计算量小、易于工程实现。并以比例微分控制为例，证明了它的可行性。通过仿真说明了各方法的特点。

In recent years, the application prospect of chaos control and synchronization in communi- cation has attracted wide attention. This paper proposes a class of chaos synchronization methods based on feedback control. Based on the error feedback, these methods are easy to realize with less computation. Its feasibility is proved by the example of proportional dif- ferential control, and the characteristics of each method are also illustrated through simula- tion.
