Torque control strategy of non-sinusoidal Brushless DC Motor based on fractional regulator

This paper deals with Torque Control Strategy of non-sinusoidal Brushless DC Motor based on fractional regulator. In this case, the dq components of the EMF are not constants. Then, the optimisation of the torque and the reduction of copper losses and torque ripples need to synthesize and to impose an optimal current waveform in dq frame. Also, the current regulators must ensure reference tracking without affecting the signal magnitudes or introducing phase shift. So we propose to investigate the fractional order regulator to control the dq currents in the park frame.
