A NEW METHOD TO REDUCE TORQUE RIPPLE IN SWITCHED RELUCTANCE MOTOR USING FUZZY SLIDING MODE

This paper presents a new control structure to reduce torque ripple in switched reluctance motor. Although SRM possesses many advantages in motor structure, it suffers from large torque ripple that causes some problems such as vibration and acoustic noise. In this paper another control loop is added and torque ripple is dened as an objective function. By using fuzzy sliding mode strategy, the DC link voltage is adjusted to optimize the objective function. Simulation results have demonstrated the proposed control method.
