| 摘 要： | 针对三相永磁直线电机动子位移以正弦规律变化时,其感应反电动势波形呈现变幅和变频的特性,提出将滞环空间矢量脉宽调制(SVPWM)电流控制应用于该整流方式。推导了三相永磁直线电机的反电动势表达式,建立三相电压源型整流器(VSR)的数学模型,详细论述了滞环SVPWM电流控制的实现方式。在Matlab/Simulink下搭建了相应仿真模型,验证了该控制方式的可行性,为直线发电机的PWM整流控制提供新思路

| Abstract: | For the three-phase permanent magnet linear motor mover displacement changes with sinusoidal law, its induced back-EMF waveform exhibits inconstant amplitude and frequency characteristics. A hysteresis space vector pulse width modulation(SVPWM)current control was proposed for this rectification method.The back electromotive force expression of three-phase permanent magnet linear motor was deduced, Mathematical model of three-phase voltage source rectifier(VSR)was established, and the realization method of hysteresis SVPWM current control was discussed in detail.The corresponding simulation model was built under Matlab/Simulink, which verified the feasibility of this control method and provided a new idea for PWM rectifier control of linear generator |
