A Review of Torque Ripple Minimization Techniques in Switched Reluctance Machine

Torque ripple is a major problem in Switched Reluctance Machine (SRM). Despite the high torque ripple and vibration, SRM has many advantages over many other machines. In this paper, the torque ripple minimization control techniques commonly used are reviewed. Torque ripple minimization can be achieved through machine magnetic design or through electronic control. Both techniques have advantages and disadvantages which will be discussed. Torque ripple production is mostly caused by the physical structure of the SRM and the basic principle of its operation. So, the basics of torque production and the physical structure of the SRM is also reviewed as part of this paper.
