摘要
针对永磁同步电动机中存在的混沌运动,提出了一种新的混沌控制方法,即对混沌动力系统增加一个具有分段二次函数x|x|形式的非线性反馈控制器,以永磁同步电动机电流的非线性反馈实现对永磁同步电动机混沌运动的控制。该控制器是一种活动控制器,它不影响原系统的参数,只需要处理一个参数,算法简单、易于实现。仿真结果表明了该方法的有效性,给出了有益的结论。
To deal with chaos in Permanent Magnet Synchronous Motor(PMSM),a method of controlling chaos by employing a dynamical nonlinear feedback controller was developed to guide chaotic motion towards regular motion.The controller was an active feedback controller without affecting the original system parameters,and was piecewise-quadratic function in the form of x|x|.The direct-axis or quadrate-axis stator current nonlinear feedback was used for chaos control.This method was simple and easy to be realized with a ...
