Reduction of torque ripple in Switched Reluctance Motor drives using Field Reconstruction Method

High grade torque control in Switched Reluctance Motors (SRM) is a key element in successful integration of this family of adjustable speed motor drives in automotive applications. Mitigation of torque pulsation in SRM drives using optimization of phase currents which are obtained from Finite Element (FE) analysis has been attempted in the past. However, long computation time of FE analysis prohibits an efficient optimization in real time. This paper incorporates an extended Field Reconstruction Method (FRM) which provides a quick and precise numerical tool for optimization purposes. Simulation and experimental results are presented to validate the claims.
