摘　　要：以表贴式永磁同步电机(SPMSM)矢量控制为基础,研究并实现了超前角弱磁控制,扩大了调速范围。在此基础上,采用一阶限幅低通滤波器对传统弱磁超前角进行滤波,消除弱磁后电机抖振现象。将定子电压相量值作为输入量,经计算、滤波后,将d、q轴偏移角度作为输出量反馈到电流环,从而实现弱磁扩速。仿真和实验证明,超前角弱磁控制能够扩大电机的调速范围,运行平稳,达到了扩速目的。Based on the vector control of the surface-mounted permanent magnet synchronous motor(SPMSM),the leading angle flux magnetic weakening control is realized and the speed adjustment range is expanded.On this basis,the first order limited-amplitude low pass filter is used to filter the traditional leading angle flux magnetic weakening control to eliminate the buffeting phenomenon of the motor.In this paper,the stator voltage phase value is taken as the input quantity.After calculation and filtering,the d and q axis migration angles are fed back to the current ring as the output quantity,so as to realize to expend the speed adjustment range.Simulation and experiment prove that the leading angle flux weakening control can expand the speed range of the motor and run smoothly,achieving the purpose of speed expansion.
