异步电动机无速度传感器控制的成就与发展

The Achievement and Development of Speed Sensorless Control of Induction Motors

本文着重点评IEEE-IES2006年第1期《感应电动机无速度传感器控制专辑》中霍尔茨教授撰写的《客座编者的话》和综述论文,两篇文章按照无速度传感器控制技术的应用和研究进展把它归纳为两大类:(1)基于电动机的基波模型,(2)利用电机的各向异性性质,与笔者所分析的三条思路不谋而合。最后,进一步指出两文所显示的先进技术。

<Guest editorial> and the survey thesis written by prof. J.Holtz published in the special issue on speed sensorless control of induction motors in IEEE-IES 2006 no. 1 are emphatically discussed and evaluated. In these two papers, according to the progress in its research and application, the method of speed sensorless control of induction motors are induced into two categories: (1) based on the fundamental model of motors, (2) exploiting the anisotropic properties of electrical machines. This conclusion happens to hold the same view with the three approaches for obtaining speed signals proposed by the author. Finally the advanced techniques demonstrated in these two papers are pointed out.
