基于电流转矩协同控制的开关磁阻电机新型直接瞬时转矩控制策略
Current-torque Coordinated Control Based Direct Instantaneous Torque Control Strategy for Switched Reluctance Motor
摘要
Abstract
In this paper,the direct instantaneous torque control(DITC)optimization of switched reluctance motor(SRM)is studied.Due to the strong nonlinearity of SRM and the limited control bandwidth of digital controller,the traditional DITC has the problems of large current pulse,high system loss and large torque ripple.Aiming at these problems,this paper proposes a current-torque coordinated control based DITC strategy on the basis of pulse width modulation DITC(PWM-DITC).The strategy innovatively introduces the current error as one of the switching conduction bases to realize the coordinated control of current and torque and complete the smooth commutation.At the same time,this paper designs parameters related to specific working conditions in the switch conduction rules,thereby reducing torque ripple.On this basis,this paper proposes a real-time modulation scheme of turn-on angle,which improves the system efficiency.This strategy effectively reduces the current pulse in the commutation interval,improves the system operating efficiency,and significantly reduces the torque ripple.Finally,the proposed strategy is verified by the experimental prototype platform.关键词
