一种改进型PWM-DITC开关磁阻电机转矩脉动抑制策略
An Improved PWM-DITC Torque Ripple Suppression Strategy for Switched Reluctance Motor
摘要
Abstract
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.关键词
