摘要:
基于电机的凸级效应，通过注入脉振高频信号并分析高频响应电流可以得到转子的位置信息，实现永磁同步电机的无位置传感器控制。文中阐述了基于脉振高频信号注入法的永磁同步电机无位置传感器控制原理，比较了几种转子极性辨识的方法，介绍了电机凸极率的测量，分析了如何提高控制精度，最后展望了脉振高频信号注入法的发展前景。
Based on the machine saliency, the rotor position information could be obtained by injecting fluctuating high-frequency carrier signal into the machine and analyzing the current response, so the sensorless control of permanent magnet synchronous machines could be realized. In this paper, the method of sensorless control of permanent magnet synchronous machines is elaborated based on fluctuating high-frequency carrier signal injection. Then the ways of rotor polarity recognition are compared, the measurement of machine saliency property is introduced, and the means to increase the control accuracy is discussed. Finally, the prospects of development of sensorless control based on fluctuating high-frequency carrier signal injection are presented.
