基于遗传算法的模糊延迟反馈控制混沌方法

摘要

Fuzzy time-delayed feedback control method is proposed by combining the merit of fuzzy control, genetic algorithm and time-delayed feedback control. To overcome the difficult of finding control gain and delay time, it uses the idea of the time-delayed feedback control to design the fuzzy controller, and then uses the genetic algorithm to search the delay time and the parameter of the controller. So the method can control chaos rapidly and robustly. The result that control Rssler and Logistic chaos by using the method shows efficiency, rapidity and robustness.%将模糊控制、遗传算法与专用于混沌的延迟反馈控制相结合，提出了适合于控制混沌的模糊延迟反馈控制方法。它以延迟反馈的思想设计模糊控制器，并利用搜索能力强的遗传算法优化延迟时间和模糊控制器的参数，从而克服了确定控制刚度和延迟时间的困难，使混沌系统控制具有更好的快速性和鲁棒性。并控制了Rssler和Logistic混沌。仿真结果证实了该方法的有效性、快速性和鲁棒性。
