摘　　要：由于闭环控制器与电力电子电路的调制策略相对独立,把鲁棒性强的控制算法与性能良好的调制策略结合起来,用于电力电子电路的控制,通过PARK变换,建立d-q坐标下的矩阵变换器模型。在空间矢量调制的基础上,设计了矩阵变换器输出电流跟踪的自抗扰控制器。仿真结果表明,该控制器稳态性能理想,动态性能良好,鲁棒性强。Since the closed - loop controller is relatively independent from the power electronic circuits, the control effect would be satisfying by adopting strongly robust control algorithm together with the excellent modulation strategy to the circuits. This paper builds the model of matrix converter in d - q frame via PARK transformation. Auto - disturbance rejection controllers of Matrix Converter for output current tracking is designed based on space vector modulation. Simulation result indicates that the controller possesses high performance dynamic characteristics and strong robustness.
