摘　　要：将用于预测永磁同步电机转子位置和转速的滑模观测器进行了改造,并构建了无位置传感器的矢量控制系统;并在此基础上提出了一种用于补偿转子位置角预测误差的改进方法。最后用Matlab仿真验证了算法的有效性,对结果进行了分析讨论。A newly designed sliding mode observer to estimate the position and speed of a surface permanent synchronous motor （SPMSM） is presented, and a position sensorless PMSM vector control system is constructed. An improved phase-compensation strategy is proposed to minimize the unwanted phase lag and forcast unknown paramter variation. To show the validity of the proposed control scheme, simulations are carried out and the results are analysed at last.
