摘　　要：双端供电模式是磁浮列车高速稳定运行的一种重要工作模式,本文建立了该模式下磁浮列车的数学模型,并提出了相应的牵引控制策略。在Simulink中搭建了控制系统仿真模型,对比了不同控制条件下磁浮列车的运行情况,仿真结果证明了控制策略的有效性。最后将提出的控制策略在硬件在环的高速磁浮交通实时仿真平台进行了验证,半实物仿真结果表明在所提的控制策略下高速磁浮列车可以可靠运行。The double-ended power supply mode is one of the important modes for high-speed maglev train. In this mode the length of the feeding cable cannot be ignored. Therefore, the mathematical model of the long stator linear synchronous motor is more complicated. This paper proposes the accurate mathematical model for the train in the double-ended power supply mode. The corresponding traction control strategy for this mode is also presented, which contains position loop, speed loop and current loop. The control strategy also contains the feedforward and decou- piing compensation methods. By comparing the operating results of the high-speed maglev train under different con- trol conditions through Simulink simulation, the results show the correctness of the control strategy. In this paper, the double-ended power supply control strategy will also be used in the hardware-in-loop real-time simulation plat- form. The testing results show that the control strategy can fulfill the stable operation of the high-speed maglev train.
