摘　　要：为提高无速度传感器异步电动机速度的实时估计与磁链的准确定向,在按定子磁链定向的矢量控制系统中,提出了模糊自适应速度估计的方法。并与传统的PI自适应速度估计进行了比较。仿真与实验结果表明,该系统具有较好的动态辨识特性和鲁棒性。In order to improve speed real time estimation and flux accurate orientation in speed sensorless asynebronous motors, fuzzy adaptive speed estimation is proposed in stator flux oriented vector control system. Comparison is carried out between traditional proportion integral （PI） and fuzzy adaptive speed estimation proposed in this paper. Verified by simulation and experiment, this system is robustness and possesses preferable dynamic performance.
