摘　　要：基于dSPACE实时仿真平台,对以输出电流为控制目标的基本滞环控制、间接电流预测控制及直接电流预测控制(27种状态)策略进行了实验验证,对比空间矢量调制策略,它们都有输入电流谐波含量大的缺点。该文以改善矩阵变换器的输入电流质量为出发点,得到了一种新的电流控制方法。新方法与基本的电流预测控制相比,输入电流的谐波有大的减少,改善了矩阵变换器的输入性能。通过dSPACE硬件实时仿真平台对新控制策略进行了实验研究,实验结果验证了该控制策略的正确性。During experiment on the conventional current hysteresis control strategy, indirect predictive-current control and direct predictive-current control based on dSPACE real-time platform, it was found that there were more input current harmonics than the conventional space vector control strategy. A new current control strategy for improving the input current quality of matrix converter was presented in this paper. Compared with the basal predictive-current control strategy, the input current harmonics was greatly reduced and the input performance of matrix converter was improved. The experiments were taken with the platform of dSPACE hardware real time simulation. The experiments results show the effectiveness of the proposed control strategy of the matrix converter.
