| 摘 要： | 针对双绕组永磁容错电机,在反电动势法基础上,提出一种改进的适用于容错电机的转子位置估计算法。利用每相绕组产生的磁链增量及单位反电动势来估算双绕组永磁容错电机转子的位置,通过锁相环技术进行误差补偿,对该方法中使用到的电机参数进行在线辨识,把辨识结果更新到转子位置估计算法中。通过该方法可以在双绕组永磁容错电机正常工作、单相故障或者多相故障容错的情况下,实现对转子位置以及转速的估计。通过MATLAB/Simulink进行仿真,验证转子位置估算方法的准确性和鲁棒性。

| Abstract: | An improved sensorless control algorithm for faulttolerant control was proposed for the dual winding FTPMM. The sensorless control algorithm, based on the back EMF method, utilized the flux linkage generated by each phase winding and the back electromotive force to estimate the position of rotor. The phaselocked loop technology was used to compensate for errors. The parameters used in this method were identified online, and the identification results were updated to the rotor position estimation algorithm. The rotor position and speed measurement could be achieved through the method in the case of doublewinding permanent magnet faulttolerant motor operating normally, singlephase fault or multi phase faults. The experiment was carried out by MATLAB/Simulink to verifiy the accuracy of the rotor position estimation method. |
