| 摘 要： | 转子位置角估算是无传感器永磁同步电动机(PMSM)矢量控制的关键,其精度直接影响控制系统的性能。基于磁链观测器的转子位置角估算方法简单易实现,但系统控制性能受磁链估算动态性能限制。为提高无传感器PMSM矢量控制系统的运行性能,对交换滤波与补偿顺序的改进低通算法进行了拓展性研究,通过MATLAB仿真验证了改进方法的可行性和有效性。

| Abstract: | The estimation of rotorpositionangle was the key to the vector control of the sensorless permanent magnet synchronous motor (PMSM), and its precision will directly affect the performance of the control system. The rotorpositionangle estimation method based on the flux observer was easy to realize, but the system control performance was limited by the dynamic performance of the flux linkage estimation. To improve the running performance of sensorless PMSM vector control system, an improved lowpass filter algorithm featured in the exchange of filtering and compensation order was studied, and the feasibility and effectiveness of the improved method were proved by using MATLAB simulation. |
