| 摘 要： | 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,并在此基础上实现了定子电阻的在线调整和定子电阻压降的补偿。在异步电机按定子磁场定向控制中,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 identify the stator flux and rotor speed is analyzed in this paper. In addition to this, online identification of stator resistance and compensation of voltage drop on stator resistor are realized. 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. |
