Magnetically levitated rail cars are expected as a new transportation system in Japan. The author used a model of magnetically levitated vehicles with many normal conducting magnets. This paper discusses the dynamics between the three coupled rail cars and the elastic rails.In this paper, I propose two types of control method; The one is Rail Oscillation Damping Control method (RODC-method), the other is Feedback Coefficients Changing Control method (FCCC-method). From an economical point of view, a light, elastic and oscillatory rail be used. In addition to this, from many geographical restrictions, a long span beam out of the standard type should be used. So I propose the above mentioned control system in which the feedback coefficients are changed one after another with the aim of damping the oscillation to match each beam by the information of its characteristics.According to the results of digital simulation, we found out; when the vehicles keep the feedback coefficients determined without RODC and FCCC methods to be constant and run on various rails, the supporting magnets come in contact with the rail; when the control circuits change the coefficients one after another with the aim of damping the oscillation so as to match the long and elastic rail on which the vehicles are running, the maglev system is stable.
