摘　　要：根据交流电机矢量控制技术特点,将交-交矩阵变换器与永磁同步电机转子磁场定向控制技术相结合,采用电流滞环控制技术实现了基于矩阵式变换器的永磁同步电机的矢量控制.给出了根据矩阵变换器输入电压状态及永磁同步电机定子电流控制的开关状态模式.最后,利用MATLAB软件对系统模型进行了仿真验证,仿真结果表明,利用交-交矩阵变换器实现永磁同步电机矢量控制是有效可行的.同时也说明了采用电流跟踪控制技术实现交-交矩阵变换器的PWM调制,概念清楚、控制简单,不需要复杂的数学计算,有利于硬件电路设计和工程实现.Based on the current hysteresis-loop control technique of AC-AC matrix converter (MC), the rotor-flux-orientation control, also called the vector control here, of permanent magnet synchronous motor (PMSM) was investigated in this paper. The switching patterns, which were determined by the input voltage states of MC and the desired stator currents of PMSM, were also presented here. The model of the vector control system was established and the simulation analysis was taken with MATLAB tools. The simulation results show that it is practical and feasible to complete the vector control of PMSM based on MC. The process of PWM modulation for matrix converters with the current hysteresis-loop control approach is fairly legible; and the hardware circuits of the system could be designed and implemented easily because of its simple control algorithm.
