摘要
介绍了几种常用的无位置传感器的控制方法,并且引入了一种新的检测技术--速度无关位置函数法来检测无位置传感器无刷直流电机的转子位置。这种方法能在转子转速近似为零到高速旋转时对转子位置进行检测,并能精确地给出换向时刻。
Several control methods of position sensorless for BLDCM were introduced, and a novel control technique that was based on the method of speed-independent position function to detect the rotor position of BLDCM was mentioned. This method may detect the rotor position at almost zero speed and even to high speed, and may also give the time of commutation accurately.
