异步电机无速度传感器矢量控制

对异步电机无速度传感器矢量控制进行了综述，介绍了开环速度估计、模型参考自适应系统、观测器估计、人工智能方法估计、空间饱和定子三次谐波电压估计、电机凸极效应估计等常见的速度估计方法，指出了各自的优缺点和适用范围。今后这方面的研究应注重于提高速度估计的精度、改进低速区控制性能以及提高系统的抗干抗能力和参数的鲁棒性。

Speed Sensorless Vector Control Drives for Induction Motor

The methods of speed sensorless vector control of induction motor are summarized. Some frequentlyused speed-estimation methods, such as open-loop speed estimation, space saturated stator 3rd order harmonics estimation and salient polo effect estimation, are introduced and both of their merits, dements and application limit have been also pointed out. In the future study, emphases should be placed on the improvement of the precision of speed estimation, low speed control feartures, anti-disturbame ability and the robustness of paramerters.
