摘　　要：为了实现面贴式永磁同步电机(sPMSM)无传感器控制,通过灰色方法对预估旋转坐标系电流的预测辨识出转子位置和速度,提出一种基于系统辨识理论的无传感器控制策略,解决了控制过程中转子速度、位置的估计问题。使用该策略建立了PMSM无传感器矢量控制系统。仿真和实验结果表明了无传感器控制策略的有效性。In order to realize sensorless control of surface type permanent magnetism synchronous motor （sPMSM）, a novel sensorless control strategy was proposed based on system identification. The grey method was used to detect the rotor position and rotor speed by the predicted current in the two -phase rotor estimation frame. And then, the sensorless vector control system of sPMSM was set up based on this position estimation approach. The experimental operation and simulation shows the validity of the proposed sensorless control scheme.
