To enhance ride comfort in the superconducting Maglev system, vibrations were reduced by controlling secondary suspension between the car body and bogie. To reduce vibrations at the relatively high characteristic frequencies of primary suspension, attention has been directed toward control using power collection coils of the on-board distributed-type linear power-generator system. Because this control can apply damping directly to primary suspension, it is considered optimal in reducing high-frequency vibrations. Using a Maglev model focusing on vertical motions, this work describes the effectiveness of reducing vibrations using damping force control of the linear generator system in for primary suspension and LQ control in the actuators for secondary suspension.
