In the PWM control strategy of switched reluctance motor

the wave signal is delayed in the excitation phase

resulting in excessive torque ripple in the switching phase synthesis. This paper analyzes this problem

combines pulse width modulation technology and improved emission principle

and proposes an improved PWM-DITC (Pulse width modulation technology-direct instantaneous torque control) control strategy. By changing the connection between the excitation moment and the demagnetization signal

the excitation phase and the demagnetization phase adopt different types of wave signals to solve the signal delay problem and reduce the torque ripple. Finally

the control strategy is verified through simulation and experiments

and it is proved that the improved PWM-DITC control strategy can overcome the problem of winding excitation delay

suppress torque ripple

demonstrate the feasibility of the viewpoint

and have good practical research value.
