In the Yamanashi Maglev Test Line, LSM is controlled with the PI controller of velocity and phase locked loop. This controller includes integrating action and compensates the position steady-state error and velocity steady-state error. Therefore the Maglev train can be controlled according to the velocity pattern accurately and the error of stopping position is within 2.5cm. Power Conversion Substation of South Group converts the power in frequency (0-46.3Hz), current (0-1015A) and in voltage (0-6, 350V). The Maglev train is controlled within these limits. However when the train accelerates and reduces maximally, it needs the power more than the limits. Naturally output power is limited within the limits, the performance of the control system is getting worse. For concrete example, at the transition from acceleration to even speed or from reduction to even speed, the overshoot or undershoot of the speed occurs. If this condition occurs at the stopping, the train moves back. These movement are not so good for the riding comfort.In this paper, we propose the Improvement method of integrating action in case of the saturation of output current. Firstly we report the configuration and basic characteristics of the method, and then we show the experiment results .

The first three-years test schedule in the Yamanashi Maglev Test Line has finished with satisfactory results at the end of March 2000. As is represented by the high speed runs at 500km/h, the test results proved the superiority of the superconducting Maglev system. This paper introduces the LSM drive system in the Yamanashi Maglev Test Line as an application of the Power Electronics Technologies.
