Abstract :
With brushless DC motors (BLDCs), current regulators in dq axes are very appreciated for sinusoidal supply. As the set current is constant, the regulator works properly. When the back-EMF is not sinusoidal, current oscillations appear in the dq regulator. A new method is proposed to avoid these regulator oscillations in case of a nonsinusoidal back-EMF
