摘要
无刷直流电机不仅保留了普通直流电机的优点,而且又具有交流电机结构简单,运行可靠,维护方便等优点,其应用和研究都受到了广泛的重视。本文介绍了无刷直流电机的工作原理和控制特点,结合国内外关于无刷直流电机无传感器控制策略的相关文献,综述了几种新型的位置检测算法,并分析各个控制算法的优缺点,最后给出了无刷直流电机无传感器控制策略的发展趋势。
The BLDCM keeps the merits of the traditional DC motors, and also has the AC motors＇ excellences, such as simple construction, operational reliability, maintainable feature. This paper introduced the fundamental principles and control characteristics and summarized some new detecting position teniques based on the documents about sensorless BLDCM＇s control strategies domestic and overseas. At the same time, the strength and weakness of these new detecting position techniques were discussed. Finally, the development tendency of BLDCM＇s control strategy was given out.
