摘要
将用于预测永磁同步电动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M atlab仿真验证了算法的有效性,对结果进行了分析讨论。
This paper presents a newly designed sliding mode observer to estimate the position and speed of a permanent synchronous motor( PMSM), and a position sensorless PMSM vector control system is constructed. Also,an improved phase-compensation strategy was proposed to minimize the unwanted phase lag mostly introduced by the low pass filter of the sliding mode observer,which is robust to unknown paramter variation. The sliding mode observer structure and its compensation method were described. To show the validity of the proposed control scheme, simulations were carried out and the results were analysed at last .
