摘要/Abstract

摘要： 齿槽转矩引起的扰动与噪声,对于在低速状态下运行的电机控制系统是极为不利的;同时齿槽转矩的存在使转子在某一时刻的到位精度受到影响。研究了一种抑制齿槽转矩的高精度定位控制方法。通过仿真和永磁同步电机实验平台,对所提方案的控制效果进行了验证。

Abstract: The disturbance and noise caused by cogging torque are unfavorable for the motor control system operating at low speed. At the same time, the presence of cogging torque affects the accuracy of the rotor at a certain moment. A high precision positioning control method for suppressing cogging torque was studied. The control effect of the scheme was verified by simulation and permanent magnet synchronous motor experiment platform.

Key words: permanent magnet synchronous machine(PMSM), cogging torque, low-speed ripple suppression, position accuracy
