Torque ripple minimization of axial laminations switched reluctance motor provided with digital lead controller

The switched reluctance motor (SRM) has great potential as an adjustable speed application due to its outstanding merits. One of the major problems is torque ripple which causes increased undesirable acoustic noise and possibly speed ripple. This paper investigates the application of a digital lead controller to the axial laminations switched reluctance motor (ALSRM) for the purpose of minimizing its torque ripples. The dynamic response of the ALSRM with the proposed controller is analyzed. The effectiveness of the proposed digital lead controller is then compared with that of the conventional PI controller.
