摘　　要：使用双空间矢量控制的矩阵变换器的等效数学模型,建立带有输出滤波器的矩阵变换器的等效电路。设计了dq坐标系下矩阵变换器的PI闭环控制系统,给出了系统在电网电压波动和负载突变时的控制方法,减小了系统在非正常工况下的输出、输入干扰。对非正常工况下运行控制策略进行了仿真和实验验证。An equivalent numerical simulation model that can describe the matrix converter using modulation stratege of dual space vector is constructed.The equivalent circuit of matrix converter with output filter is analyzed. Closed-loop control system with PI con- troller is designed. Control methods while voltage fluctuation and load break are presented,which decease the input and output dis- turbance on abnormal condition.The control strategy on abnormal condition is verified through simulation and experiment.
