State Of The Art Of Switched Reluctance Motor For Torque Ripple Minimization
Switched Reluctance Motor (SRM) is a type of synchronous AC machine that converts the reluctance torque into
mechanical power. Torque pulsations are inherent in SRM due to the doubly salient structure of the machine. The SRM
offers similar overall efficiency to an induction motor of the same rating since the windage and friction losses are
comparable. Indirect torque control methods using Torque Sharing Functions (TSF) is applied for the minimization of the
torque ripple in switched reluctance motor. The most classical and easily implemented controller is the hysteresis controller.
The increase of the current ripples at steady state and the production of a variable switching frequency in hysteresis
controller can be reduced by using sliding mode controller. This paper reviews their merits and limits based on a survey of
the available literature to minimize torque ripple in Switched reluctance motor.
