Magnetically levitated (MAGLEV) vehicle systems have been researched for future high-speed transportation. It is especially important to investigate their dynamic characteristics from the viewpoint of running stability, safety and ride quality at high speed. This paper deals with repulsive-type MAGLEV systems using electrodynamic suspension (EDS). Although the EDS is inherently stable, the damping force is not large enough to suppress the vibration excited by guideway irregularities and other disturbances. Therefore, this paper investigates theoretically and experimentally the damping force control of EDS systems with a hybrid magnet configuration of a permanent magnet and an additional electromagnet of which the current is compensated by a feedback control loop. The dynamical characteristics are analyzed by an experimental setup in which a one-degree-of-freedom mass is suspended above an aluminum rotating plate. According to the experiment, the damping coefficient is significantly increased by the additional control circuit.
