| 摘 要： | 基于延时反馈控制方法和可测状态变量周期信号的特征,提出了一种自适应延时反馈混沌控制的新方法。应用时仅需要给定延时时间和信号增益的任意初值即可,避免了事先确定此类控制参数的繁琐过程。通过对Rossler系统和两自由度机翼系统混沌控制的数值研究,结果表明无论对系统的状态变量的摄动,还是对系统参数的摄动,该方法均能有效将混沌状态控制到期望的周期状态,并且缩短了控制时间。 |

| Abstract: | According to the characteristic of the method of controlling chaos by self-feedback and period signal of the accessible state variable,the new method of adaptive delayed control by self-feedback has been made.In practice,we only give certain initial values of delayed time and signal gain,avoiding the clumsy process of determining the control parameter first.By applying the method into Rossler system and two-degree-of-freedom airfoil system,it indicates that the method can effectively control chaos,whether perturbation of certain state variable or systemic parameter of chaotic system,and can effectively shorten control time. |
| Keywords: | control of chaos delayed self-feedback adaptive control autonomic system |
