摘要
为了解决模型预测控制在双极型矩阵变换器控制中的开关周期不固定以及空间矢量调制控制策略的动态性能较差,提出了使用无差拍控制算法控制双极型矩阵变换器。无差拍控制通过预测模型对输出电压矢量以及电源电流矢量进行最优矢量组选择并进行调制。该方法良好地控制输出与输入电流波形,且对直流侧的电压有优化作用,动态性优异,对于网侧电流也有正弦化的作用。MATLAB作为算法的仿真实验软件,仿真结果有力地证明了该算法的理论研究。
In order to solve the characteristics of the variable switching period of model predictive control and the poor dynamic performance of space vector modulation control strategy,deadbeat control is proposed and innovatively applied to the control of two-stage matrix converter.The deadbeat control modulates the output voltage vector and the input current vector through the predictive model.This algorithm can control the output and input current waveform well,and can optimize the voltage on the dc-link,and forces source current sine.The simulation results based on MATLAB prove the above theoretical analysis strongly.
