摘要
为了解决永磁同步电机在复杂环境下转矩脉动大,转速响应速度慢的问题,根据永磁同步电机的数学模型,设计了一种模糊PI控制系统,并采用电流转速双闭环的矢量变换控制方法驱动永磁同步电机。经分析仿真实验结果可知:该控制系统解决了传统PI控制器存在的转速超调量大;转速响应慢;转矩脉动大等问题,有良好的动静态特性。
In order to solve the problems of large torque ripple and slow speed response of permanent magnet synchronous motor(PMSM) in complex environment, a fuzzy PI control system is designed according to the mathematical model of PMSM. The vector transformation control method of current and speed double closed loop is used to drive the PMSM. The simulation results show that the control system solves the problems of traditional PI controller, such as large speed overshoot, slow speed response, large torque ripple and so on, and has good dynamic and static characteristics.
