一类混沌系统的动态输出反馈控制

Dynamic output feedback control for a class of chaotic systems

为了对一类混沌系统实施控制,提出了利用新的控制器来控制混沌系统。以往的混沌控制方法只针对个别特殊的混沌系统,而利用动态输出反馈的方法能控制一类混沌系统,这方面的工作以前也曾有过。利用李雅普诺夫稳定理论,结合线性矩阵不等式优化方法,分析了系统的稳定性。数值仿真也表明了所提出的控制策略的有效性。

A new controller is proposed to control a class of chaotic systems. Since the available chaotic control methods are only applied to the special chaotic systems, a dynamic outputs feedback controller can control a class of chaotic systems. A well-known Lyapunov stability theorem combining with linear matrix inequality optimization approach is utilized for the stability analysis of the method. The result of numerical simulation show that the above proposed scheme is effective.
