基于滑模变结构永磁同步电机混沌跟踪控制

Chaos tracking control of permanent magnet synchronous motor based on sliding mode

在某些参数的情况下,永磁同步电机(PMSM)会出现混沌现象。利用滑模控制变结构控制原理,可以将含有扰动的系统混沌轨道先后控制到任意固定点和周期轨道,依据李雅普诺夫稳定性原理证明所设计的控制器可使得该系统逐渐达到稳定。仿真结果进一步验证了该方法的有效性,对电机运动的稳定性具有较好的价值。

In some parameters, permanent magnet synchronous motor （PMSM） was a chaos phenomenon. By using sliding mode control principle, the chaos system with distraction was gradually controlled to arbitrary chosen fixed points and periodic orbits. The system was gradually stable based on the Sliding Mode control principle of Lyapunov. The efficiency of this method was further demonstrated by the simulation results, and the stability of PWSM was in a good value.
