永磁同步电动机转速专家控制

Expert Control for Speed of Permanent Magnet Synchronous Motor

针对永磁同步电动机(PMSM)的动态数学模型、参数改变及易受外界干扰,提出了一种基于专家控制的PMSM转速控制系统.利用专家控制算法对PMSM控制系统进行了Matlab仿真分析,并与PI控制算法进行了比较,验证了所提控制系统具有良好的动态特性和鲁棒性.实验结果表明,该控制系统响应速度快,超调小,系统运行稳定.

In this paper, a rotating speed control system based on the PMSM of expert control is proposed, which aiming at solving the problems of being liable to outside disturbances for the permanent magnet synchronous motor dynamic mathematical model and the parameter variations. It processed the MATLAB simulation and analysis to the PMSM control system using expert control experience algorithm, and compared with PI algorithm to validate that this system has a good dynamic characteristic and robustness. The final results show that this control system has fast response, little over regulation; meanwhile, the system is stable.
