摘要
无位置传感器技术是开关磁阻电机(Switched reluctance motor,SRM)系统研究的一个重要方向。该技术的研究可以进一步提高SRM的系统集成度,增强系统的高速性和环境适应性,充分发挥SRM的强容错能力和高可靠性。本文针对启动和低速运行以及中、高速运行等不同运行状态对目前国内外所研究的无位置传感器方法进行了分类讨论,并评述各种方法的优缺点;最后对该技术所亟需解决的关键技术和未来发展趋势进行了分析和展望,以期对未来开关磁阻电机系统的深入研究和拓宽应用提供参考。
The sensorless technique is an important research branch in switched reluctance motor （SRM） drives system. The research of the high performance sensorless technique can further improve the sys- tem integration, enhance the high speed capability and harsh environment adaptability, and make full use of the strong fault-tolerant capability and high reliability of SRM. Aiming at the starting-low speed operation, and the medium-high speed operation conditions, this paper classifies and discusses the research status of the sensorless schemes, and reviews their advantages and disadvantages. Finally, the key technologies and future development trends of the sensorless technique are analyzed, which will provide important reference for the in-depth study and broadening the application of the SRM drive system.
