摘　　要：结合矩阵式变换器双空间矢量调制算法与电机矢量控制原理,对某船用永磁同步电机进行仿真研究.设计涵盖电机启动,正常运行及能量反馈各状态的实验.仿真结果表明电机转速能保持设定值,转矩响应迅速,输入侧电流总谐波畸变率符合规范要求且能实现能量反馈.At present, there are numerous problems in converting technique for marine electric propul- sion system, such as low power density, difficult energy feedback and limited output frequency. Based on the series problems, matrix converter, a kind of ideal converter, could be supplied to solve the problems. For a marine permanent magnet synchronous motor （PMSM）, the matrix converter＇ s double space vector modulation is combined with PMSM＇s vector control to run simulation. Designed experiment could switch the state of motor from the first quadrant （normal operation） to the second quadrant （energy feedback）. The simulation result indicates that the control strategy could achieve good speed and torque response with low current harmonics. In addition, the energy feedback could be achieved simultaneously.
