The design and artificial realization of a controller of pulse coupling feedback 总被引:1,自引:0,他引:1 下载免费PDF全文
In this paper a controller of pulse coupling feedback (PCF) is designed to control chaotic
systems. Control principles and the technique to select the feedback
coefficients are introduced. This controller is theoretically studied with a
three dimensional (3D) chaotic system. The artificial simulation results
show that the chaotic system can be stabilized to different periodic orbits
by using the PCF method, and the number of the periodic orbits are
2n× 3mp (n and m are integers). Therefore, this control method is
effective and practical. 相似文献

非线性反馈控制单模激光Haken-Lorenz混沌系统 总被引:1,自引:1,他引:0
提出一种变量非线性反馈(VNF)方法控制混沌系统.介绍了该方法的控制原理以及反馈系数的选取原则,以单模激光Haken-Lorenz系统为例对非线性反馈控制方法进行了理论研究.仿真结果显示,通过恰当的选择反馈系数k,使系统的最大李雅普诺夫(Lyapunov)指数由正值转变为负值,相图中系统的轨迹由混沌吸引子转变为周期数为2n×3mp(n、m为整数)的周期轨道.通过与线性反馈控制结果对比发现,非线性反馈控制方法简便有效,控制速度快. 相似文献
