| 摘 要： | 基于前馈解耦控制策略,研究了三相电压型PWM整流器的建模与控制问题。首先,在d-q旋转坐标系下建立了三相电压型PWM整流器的数学模型,给出了三相电压型PWM整流器的双闭环控制结构,按此方法确定了电压、电流PI调节器的设计方法。仿真结果表明该方法能使所设计的PWM整流器运行于单位功率因数,输出的直流电压稳定在期望值且具有快速的动态响应,满足了设计要求。

| Abstract: | Based on feed-forward decoupling control strategy, the model and controller of three-phase voltage source PWM rectifier are presented. First of all, a mathematical model of three-phase voltage source PWM rectifier is established in the d-q rotation frames. The double loop system is designed based on feed-forward decoupling strategy, and three PI controllers are designed. The simulation results show that this method can make PWM rectifier run with unit power factor, the output DC voltage stabilize on the desired value with the fast dynamic response. The characteristics meet the design demands. |
