An Improved DTC Strategy in SRM Application

In order to reduce the torque ripple of switched reluctance motor in traditional direct torque control(DTC) on the basis of its strategy improvements,an improved DTC control strategy is presented by the switched reluctance motor(SRM) stator winding voltage,current,as well as real-time detection of the position angle of the rotor turned,and then get the motor running real-time torque,built in MATLAB model and simulation.The simulation results show that the improved direct torque control method,the motor to get better dynamic and static performance,largely suppress the torque ripple of SRM.Significantly superior to conventional control methods in the control effect of great significance in the study of the speed control system of switched reluctance motor(SRM) applications is presented.
