Abstract:

Recent research efforts have increasingly focused on Switched Reluctance Motors (SRMs), with extensive investigations reported for applications ranging from transportation and aerospace to industrial and residential systems. Torque ripple in an SRM is mainly caused by the dependence of electromagnetic torque on rotor position and the discrete nature of phase excitation. Consequently, numerous strategies have been recognized to reduce torque ripples using both direct and indirect approaches. Through the smoothing of the torque output from the motor, these methods aim to lessen vibration and noise. There have been a lot of studies conducted regarding minimizing torque ripple in SRM drives, and various approaches have been presented to address this problem. The objective of this review is to explore the various strategies and techniques developed to reduce torque ripple in SRMs.The goal of the survey is to study the approaches and models that have been established to lower the SRM’s ripple torque. The reviews cover the pre-processing techniques to reduce torque ripple, such as changes to the power electronics, controller algorithms, and motor design. It also gives the surveys related to the SRM using current shaping, predictive control, and DTC, respectively. The different metrices used in the works were also exposed in the analysis part of the paper. By examining several methods used in the literature, the work provides a thorough overview of the torque ripple minimization technique in SRM drives and draws attention to the effectiveness, challenges, and future possibilities of this sector.
