一类混沌系统的鲁棒同步控制

Robust Synchronization Control of a Chaotic System

基于非线性状态反馈线性化、最优控制及李雅普诺夫方法 ,对连续时间标量混沌信号的鲁棒同步控制进行了研究。在一定的假设条件下 ,得到了一个简单、性能优良的控制器 ,且是大范围渐近可同步的。对一个四阶自治混沌系统的仿真研究表明了该控制策略的有效性。

This paper is concerned with the robust synchronization control problem of continuous time scalar chaotic signal.It is based on the nonlinear state feedback linearization,optional control and Lyapunov method.Under some certain assumptions,we have obtained a simple controller with good performances.With the controller,chaotic system is global and asymptomatic synchronous.An application for the synchronization of a four-order autonomous chaotic system is presented.\;
