Direct Torque Control Technology of Switched Reluctance Motor Based on Torque Ripple Minimization

The switched reluctance motor has disadvantages such as greater torque ripple,more serious noise and vibration problems than other drive systems.The direct torque control technology is used in the switched reluctance drive systems,which takes the torque ripple minimization as control goal.The simulation model of direct torque control of switched reluctance motor is built based on the theory.The results show that the amplitude of the flux can be well controlled in hysteresis band,the motor's torque ripple and noise problems are effectively inhibited.
