摘要
通过简单的线性状态反馈方法 ,分别在系统参数已知和未知的情况下研究了陈氏混沌系统的控制问题 .当参数已知时 ,给出了反馈增益的范围 ;当参数未知时 ,设计了一自适应控制器 ,它克服了一般的自适应控制器中控制律不连续的缺点 .通过实验仿真证明了所给方法的有效性 .
The control of Chen's chaotic system when its parameters are known a priori or unknown is studied by means of a simple linear state feedback method. When the parameters are known a priori, we show the variation range of feedback gain; and when the parameters are unknown, an adaptive controller is designed, which overcomes the drawback that the control is discontinuous in a common adaptive controller. Finally the simulation results vertify the effectiveness of our proposed method.
