摘　　要：地铁列车用直线感应电动机(LIM)驱动,具有转弯半径小、爬坡能力强、结构简单、体积小、维护少、运行可靠等众多优点,已经在城市轨道交通中得到了很好的应用。为进一步推广、应用直线电机地铁,介绍了一条自主设计的直线感应电动机驱动的地铁试验线。采用无线遥控控制,设计了基于空间矢量脉宽调制(SVPWM)的控制系统,在实验室中进行了模拟试验。试验结果表明该套控制系统能满足机车在试验线上运行时的各种工况并可靠地工作。The subway train driven by linear induction motor （LIM）has the merits of small turning radius, good climbing ability, simple structure, small size, little maintenance, reliable operation etc.. It has been well used in urban rail transit. In order to further promote and apply linear motor subway, a self-designed subway test line driven by linear induction motor was introduced. Using wireless remote control, a control system based on space vector pulse width modulation （SVPWM） was designed, simulative test was taken in the laboratory. The experimental results show that this control system can meet the various working conditions when the locomotive is running in the test line and work reliably.
