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.

Key words:matrix converter;model predictive control;switching frequency;modulation strategy;harmonic
