摘要
针对现有滞环控制策略存在的不足,提出一种不定频滞环的SVPWM电流控制方式。它主要是将滞环控制与SVPWM控制相结合,通过三相PWM电压型整流器(VSR)空间电压矢量的实时切换,将电流限制在一个给定滞环内,从而获得电流的高品质控制。介绍了此控制策略的原理,并在Simulink上进行建模仿真,得到的结果证明不定频滞环策略可行。
Against the shortcomings of present hysteresis control, this paper proposes a method oi space vector pulse width modulation(SVPWM) current control based on indeterminate frequency hysteresis.This controUing project combines SVPWM controlling with hysteresis controlling.With switching of three-phase PWM voltage source rectifier(VSR) space voltage vector,the current is limited within a given hyteresis for coming ture current high-quality control.This paper introduces the principle of the control strategy and modeling and simulation in Simulink, simulation results verify the feasibility of this strategy.
