| 摘 要： | 针对永磁同步正弦波电机（PMSM）的无速度传感器在低速以及零速附近运行时利用反电势进行难以估算位转子位置的问题,提出引用高频注入（HFI）方法进行估算.在电机模型的基础上,通过对静止坐标上的电压旋转注入和旋转坐标上的d轴电压注入方式这两种信号注入方式比较,得出两种注入各自的特点,且在两种方式中PMSM的无速度传感器电流谐波效应均存在一个周期性的干扰.

| Abstract: | During the speed sensorless of permanent magnet synchronous motor(PMSM) operating in low speed and near zero velocity,rotor position is hard to estimate using the counter emf.On this basis,reference method of high frequency injection(HFI) is proposed for estimation.On the basis of the motor model,through comparison by two signal injection patterns of the voltage stationary coordinates rotation injected and rotating coordinate d shaft voltage injected,characteristics of two implantation respective are drawn.... |
