Abstract
In the Yamanashi Maglev Test Line, the location of the train is detected with the inductive radio system. The inductive radio system is very reliable and accurate. However using the inductive radio system, we have to lay the cross inductive cable along the guideway accurately and set up the detecting system of train's location in each power conversion station. Therefore the cost of construction and maintenance is very expensive. Moreover, from the redundancy point of view, it is necessary to examine the other method of detecting train's location, in case of inductive radio system down.
We have already proposed a new train's location detecting system using the phase of Electromotive Force (EMF). In this system, the reduced-order state observer estimates the phase of EMF. Therefore the inductive radio system is not required. We have reported the configuration and the basic characteristics of the EMF observer. In this paper, we report the experimental results of running test at the speed of 300km/h_??_0km/h in the Yamanashi Maglev Test Line. We confirm the performance of velocity and current control with EMF.
