基于低通滤波器的高速磁悬浮鼓风机无传感器BLDCM驱动控制

This paper develops the brushless dc motor sensorless control strategy for a high-speed maglev blower. The sensorless techniques are based on a phase voltage comparator and a nonlinear offline compensator. The nonlinear offline compensator is used to compensate for the phase delay of the back electromotive force due to a low-pass filter; the phase voltage comparator is used to compensate for varia...
