Abstract:Precise commutation is a significant factor for im-proving the operational efficiency of the brushless DC motor. However, there exists residual error with the motor of three-phase asymmetric back electromotive force (TAEMF) under conventional commutation error correction methods. For solving this problem, a three-parallel channel (TPC) error compensation strategy is proposed. First, the source of error caused by the TAEMF is analyzed. Then, the feedback quantity related to the commutation error is constructed, which is based on the corre-lation between the virtual neutral point relative to the
