Development of LSM control system for super speed maglev

As a propulsion device for super speed maglev with 500km/h level, the powerful linear synchronous motor(LSM) is necessary. To control the LSM, the precise position data of high speed running maglev should be detected and transmitted to the inverter controller which provides the synchronized current to the LSM stator attached on the guideway. And to minimize the power input to the stator, the whole guideway is devided into several sections and the power is supplied to the only one section which the train is running on. In this case, precise section change control is needed to mitigate the vibration and noise. In this study, first, the infinite loop type LSM and section control testbed is developed. Then, LSM and section control algorithms are applied to the testbed and the feasibility of derived control techniques are verified through the experiments.
