线性反馈控制混沌的分析

Analysis of Linear Feedback Control of Chaotic System

以永磁同步电动机为例,研究如何利用线性反馈控制混沌。首先在理论上分析该方法并构造李亚普诺夫函数,然后通过实验仿真来验证它的正确性。结果表明:利用线性反馈可以很好地消除混沌,使方程达到一个稳定的状态。

The paper mainly deals wiih how to control chaos by means of linear feedback control taking permanent-magnet synchronous motor as an example. Firstly, analyze the control method in theory and construct Lyapunov functions, and then test its correctness by simulation experiment. Result shows that chaos of system can be well controlled by linear feedback; thereby the system reaches a stabilized state.
