The magnetically levitated vehicle (Maglev) system is the most promising system for high speed mass transportation in the near future. We have carried out running tests at Yamanashi Maglev Test Line since April 1997, and attained the speed of 550km/h in December, the world speed record of the railway systems.
In Yamanashi Maglev Test Line, the vehicles are automatically driven by three pairs of inverter in the power conversion station. The automatic drive control system requires the instantaneous location of the vehicle to generate the current references for LSM. The location signal is detected by the inductive radio wires along the guide-way. And it is superposed with some disturbances, which may cause the fluctuation of the propulsion force.
On the other hand, load variation occurs according to the change of vehicle's weight and running resistance.
We need to design the drive control system considering ride quality as well as speed following performance in spite of the distorted location signal and load variation.
In this paper, we describe the design procedure, the drive control characteristics and the test results in the Yamanashi Maglev Test Line.
