Effectiveness of Power Electronic Controllers in Mitigating Acoustic Noise and Vibration in High-Rotor Pole SRMs

This paper presents a comparative evaluation of power electronic control approaches for vibro-acoustic noise reduction in High Rotor-Pole Switched Reluctance Machines (HR-SRM). It carries out fundamental analysis that can be used to target acoustic and vibration reduction. Based on the comprehensive study, four candidates have been identified applied HR-SRM drive evaluate their effectiveness identify challenges. These methods include phase advancing, current shaping based field reconstruction, random hysteresis band with without spectrum shaping. The theoretical background, implementation, performance each method are presented detail. Comparative studies from simulation experimental measurements most effective solution configuration.
