摘要
Abstract
According to the sensing theory of speed-independent flux linkage function, an improved scheme was proposed for BLDCM sensorless control without the stator inductance. The commutation instants of BLDCM were obtained from the calculation in real time by measuring three phase terminal voltages and DC link current and utilizing the stator resistance. Based on this scheme, it was easy to realize sensorless control. The proposed method was simple to realize and convenient to control, and it could accurately detect the rotor position signal. An improved start scheme was proposed by researching on the short voltage pulse detection method. The methods metioned aboved were tested through experiments and the anticipated results are achieved.关键词
