| 摘 要： | 分析了几种常用磁链观测方法,提出一种改进的MRAS(模型参考自适应)磁链转速观测器,同时辨识了定子磁链和转子转速。在异步电机按定子磁场定向控制系统中,采用定子电阻压降补偿和电流转矩分量的闭环控制,实现了定子磁链的控制,系统具有较好的鲁棒性。

| Abstract: | An improvement MRAS （model reference adaptive system） flux and speed observer which identifies the sta- tot flux and rotor speed is analyzed. Stator resistance compensation and torque component of current closed loop control strategy is adapted in stator flux oriented sensorless vector control of induction motor system. Stator flux control is realized and the system has a good robust. |
