Abstract
To control the linear synchronous motor(LSM) which is used for super speed maglev, the precise position data of high speed running train is needed for generation of synchronized current which is supplied to the stator attached on the guideway. Also to reduce the amount of current 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. The poor performance of position detection causes the degradation of LSM propulsion efficiency. Also, the poor section change due to bad LSM control causes the fluctuation of vehicle, which decreases the comfortability. In this study, to evaluate the influence of position detection performance on the LSM and section control, the infinite loop type testbed is developed, and improvement method was investigated.
