摘要
永磁同步电机的矢量控制系统由永磁同步电机、功率变换器、控制器以及位置和转速估计等环节组成,而位置和转速估计在很大程度上影响着整个系统的运行特性和控制精度。本文研究了无位置传感器的情况下对永磁同步电动机的转子磁极位置的检测方法,着重研究了静止和低速状态下的无位置传感器的转子磁极位置检测方法。
The vector control system of PMSM consists of a PMSM、power converter,controller as well as position and speed prediction components.The detection to rotor position and speed will to the great extent effect the performance and resolution of the system.This paper investigates the detection to a sensorless PMSM rotor position,the standstill and low-speed situations are especially emphasized.
