Abstract
In this paper, a novel id*=0 vector control method for a BLDCM with neither sinusoidal nor trapezoidal back-EMF (the main part is considered as sinusoidal with high-order harmonics) is proposed. By this method, the iq for a constant torque to produce is calculated through coordinate transformation, and the reference iq is tracked by vector control in the dq0 frame. The simulation results show that this control technique can effectively minimize the torque ripple caused by high-order harmonics of the back-EMF.
