摘要
提出了一种简单但有效的永磁同步电机转子位置观测的新方法.该方法通过在电机定子绕组中注入高频电压,利用电机的凸极效应,通过对电机绕组端电流的处理计算,准确地估算出电机的转子位置.还提出了在电机静止状态下检测转子初始位置的新方法.仿真结果显示了所用方法的有效性和可行性.
A simple but effective method to observe PMSM rotor position is presented in this paper. A high frequency voltage is injected into the motor and it will cause a little change of current signal because of the anisotropy of the machine. By processing the current in the armature, this method can calculate the rotor position accurately. This paper also presents a new way to observe the original rotor position when PMSM is standstill. The results of simulation show that this method can work feasibly and effectively.
