Torque Ripple Minimization of switched reluctance drives - A survey

Torque ripple is a major problem of switched reluctance motor drive system, which causes undesirable vibration and acoustic noise. The magnetization pattern of the individual phases together with the static characteristics of the motor dictate the amount of torque ripple during operation. Both machine design and electronic control approaches have been used for Torque Ripple Minimization in SRMs. This paper presents an extensive review of the origin of torque ripple and the approaches adopted for Torque Ripple Minimization.
