| 摘 要： | 文章提出了一种采用电流矢量PWM控制的非线性控制策略，该方案通过电流矢量PWM控制来跟踪电流指令，从而简化了电流型PWM AC／DC变换器波形发生。在建立电流型PWM AC／DC变换器d-q模型基础上，采用输入输出线性化方法实现了解耦控制，给出了理论分析和调节器参数整定算法，并利用Mallab对控制策略进行了仿真，获得了预期效果。

| Abstract: | In order to achieve high performance control for cur-rent -source PWM AC /DC converter,a n on -Linear control strategy with current vertor contro l is proposed in this paper.The proposed scheme simplifies the wave form control of current -source PWM AC /DC converter which tra cks the AC side current references.On the other hand,this p aper provides decoupling and linearization of bath d and q components of AC side currents us-ing input -output linearization based on d -q model.Further-more,the theoretical analysis and c ontroller design are presented.Simulation results are provided to v erify the operating principle of the scheme. |
