Abstract

The magnetically levitated railway has great promise in solving the problems associated with maintenance requirement, noise level and speed limit. Among various magnetic levitation systems, the authors consider the attractive-force-type levitation system using a normal conducting magnet the most promising. Since this system is inherently unstable, some closed-loop control is indispensable in stabilizing it. This paper designs the optimal controller for an attractive-force-type levitation system based on optimal control theory. The proposed design method is applicable not only to the attractive-force-type levitation system but also to the repulsive-force-type levitation system using a superconducting magnet.
