基于模糊PID的永磁同步电机调速系统

针对传统PI控制在永磁同步电机调速系统中存在适应性、鲁棒性差的问题,提出模糊自适应PID控制。将传统的PID与模糊控制结合,构造了模糊PID与空间矢量脉宽调制(SVPWM)的永磁同步电机的矢量控制系统。仿真结果表明,该系统不仅具有良好的静态、动态性能,而且还具有良好的适应性与鲁棒性。

A Permanent Magnet Synchronous Motor Speed Control System Based on Fuzzy PID

In view of the poor adaptability and robustness exhibited by traditional PI control in the permanent magnet synchronous motor speed control system, a proposal of the fuzzy adaptive PID control has thus been made. The vector control system of permanent magnet synchronous motor (PMSM) with fuzzy PID and space vector pulse width modulation (SVPWM) can be constructed by combining the traditional PID with the fuzzy control. The simulation results show that the new system is characterized with not only an improved static and dynamic performance, as well as with a good adaptability and robustness.
