This article introduces a novel optimum current profile generation technique based on the simultaneous reduction of torque ripple and radial force ripple for acoustic noise and vibration reduction in switched reluctance machines (SRMs). Optimum current profiles at various operating points are generated through electromagnetic finite element analysis (FEA) aided dynamic simulations. Multiphysics simulations are performed to evaluate the noise, vibration, and harshness (NVH) performance of the SRM drive for both conventional and proposed current waveforms, which show significant comparative improvements for the proposed methodology. A prototype SRM rated at 100-kW power with a maximum operating speed of 4250 r/min is constructed for testing. The proposed method is tested against the conventional current profiling technique at numerous operating points, encompassing a wide operation speed range. Test results are cross matched against simulation results, which validates the accuracy of the implemented modeling process. Moreover, test results show significant improvement in NVH performance and validate the effectiveness of the proposed methodology. A peak improvement of 19.93 dBA is seen from experimental results for the proposed current profiling technique at 800-r/min 200-Nm output torque condition.
