摘　　要：针对永磁同步电动机直接转矩控制的特点,本文提出一种将矩阵式变换器技术和永磁同步电机直接转矩控制技术相融合的控制策略。该策略将矩阵式变换器的优点和直接转矩控制的优点相结合,实现对永磁同步电机的高效控制,运用MATALAB/SIMULINK仿真工具箱对系统模型进行仿真实验,仿真结果表明:采用该控制策略,系统具有良好的传动性能和动静态性能,可实现能量的双向流动。Aiming at the characteristic of permanent magnet synchronous motor direct torque control, the paper puts forward a kind of control strategy combining matrix converter technology with permanent magnet synchronous motor direct torque control technology. This strategy has the advantages of matrix converter and direct torque control, which can control effectively of the permanent magnet synchro- nous motor. The system model simulation experiment was carried out by Using MATALAB/SIMULINK tool box. The simulation results show that the system has good dynamic and static performance and transmission performance, and it can realize two -way flow of energy.
