【摘要】 简要介绍了永磁电动机的运行方式,总结了国内外关于永磁电动机控制技术的研究成果。按 6个方面分析对比永磁电动机各项控制技术的应用范围及其优缺点,其控制技术正在从传统的有位 置传感器的闭环PID控制过渡到无位置传感器的智能控制,其调速范围、转矩脉动、系统鲁棒性等性 能都在不断提高。更多还原

【Abstract】 The running manners of permanent magnet motors have been introduced briefly. The research achievement on the control technology of permanent magnet motor at home and abroad is summarized. The advantage and disadvantage and its application range of every control technology is analyzed and contrasted in six aspects. The control technology is now turning from traditional PID feedback control with position sensor to intelligent control with position sensorless. The behavior of robustness of system, torque ripple, and speed range has all been improved.更多还原
