基于HGAPSO算法的永磁同步电机PI参数整定

摘要

目前, 高性能永磁同步电机控制中对PI参数进行整定时, 往往需要采用比较繁琐的人工试凑法, 但得到的整定结果无法保证系统的高精度控制性能.针对这种情况, 采用HGAPSO智能寻优算法来计算永磁同步电机PI控制器的Kp、Ki参数, 经过该算法寻优之后得到的结果能够使永磁同步电机的转速响应时间比较短, 超调量比较小, 达到更好的控制效果.%At present, in the control of high performance permanent magnet synchronous motor, the method of manual trial and error is often needed to complete PI parameters. The final setting result cannot guarantee the high precision control performance of the system. In view of this situation, HGAPSO intelligent optimization algorithm was adopted in this paper to calculate the Kpand Kiparameters of the permanent magnet synchronous motor PI controller. The results obtained after optimization of the algorithm can make the permanent magnet synchronous motor speed response time shorter, overshoot less, and stator current curve more perfect.
