摘要:不同的矩阵变换器调制策略与系统运行控制之间不协调会造成系统干扰，为此，本文提出一种调制模型预测控制（modulation model predictive control，M²PC），基于经典的模型预测控制（model predictive control，MPC）改进控制策略，对矩阵变换器系统的输入输出性能进行优化。M²PC策略不仅包含MPC策略的多种优良特性，而且能够避免由MPC策略引起的可变开关频率，降低系统输入输出谐波，控制过程简单，不需要引入其他变量，应用前景良好。最后对M²PC策略进行仿真和实验，证明了该策略的优越性。

Abstract:The system interference is often caused by the incompatibility between the different modulation strategies and the system operation control.A modulation model predictive control （M²PC） was proposed based on the classical model predictive control （MPC）.Furthermore，the control strategy was improved to optimize the input and output performance of matrix converter system.The selected M²PC strategy not only contained a variety of excellent characteristics of MPC strategy，but also avoided the variable switching frequency caused by MPC strategy，reduced the system input and output harmonics.The control process was simple and did not need to introduce other variables so it had a good application prospect.Finally，the proposed strategy was simulated and tested，which proved the superiority of the proposed strategy.
