A Review of Torque Ripple Control Strategies of Switched Reluctance Motor

Doubly salient, single energized Switched Reluctance motor is eminently suited for Industrial application of variable speed control .SRM drive is most suited for low cost and variable speed operations. But the major drawback in Switched Reluctance Motor is High torque ripple, mechanical vibration and Acoustic noise. Due to its nonlinearity and doubly salient structure torque ripple becomes inevitable. This paper discussed about the outset of torque ripple and the appropriate methods used so far to diminish the torque swell in Switched Reluctance Motor. Results obtained from the review of all the Torque ripple Minimization techniques are presented. From the results it has been concluded that DTC and DTC with PI &Genetic PI controller gives the least torque ripple when it is used in Switched Reluctance motor drive.
