摘　　要：无刷直流电动机的无位置传感器控制技术是业内近二十年来的一个重要研究方向。已经有多种技术见诸报道。文章对基于反电势的无传感器控制方法作一综合介绍和比较。Position sensorless control is often required in PM BLDC motor drives. Many categories of sensorless control techniques have been developed in the last two decades, whilst the most popular category is that based on back EMFs. All those EMF-based sensorless control strategies are reviewed and compared.

关 键 词：无刷直流电动机 无传感器控制 反电势 过零点 电压积分 锁相环
