摘　　要：提出用一套控制单元实现2套独立主电路控制,驱动2台永磁同步电机的矢量控制技术。采用基于转子磁场定向的矢量控制策略,输入的力矩指令经过MTPA控制策略,进行双电流内环控制。与原异步转差控制系统相比,该技术控制精度高,动态响应快,将更适合于电车复杂的运行工况,且永磁电机无需励磁电流,节能效果更明显。A novel vector control method for driving double PMSM based on one control unit commanding two independent main circuit loops was proposed.Using vector control of the rotor filed oriented,input torque command was given with the maximum torque current control principle to implement double current inner loop.Compared with the original asynchronous slip control system,the new method had the advantages of high control precision,fast dynamic response,more suiting for tram car complex operating conditions,no permanent magnet motor excitation current,and obvious energy-saving.
