We have proposed a magnetic levitation control system for a sheet steel and confirmed the realization by the digital control experiment. However, the case in which only the levitation control is applied for the steel plate, it has no horizontal restraining force in the traveling. Then, the electromagnetic actuators are installed in order to control the horizontal position of the levitated sheet steel. The electromagnetic attractive control forces of the actuators are given for the faced two edges of the levitated sheet steel from horizontal direction. In this paper, the suppression effect of elastic vibration of the levitated sheet steel in the horizontal noncontact positioning was reported. The results of experiment showed that the elastic vibration of the sheet steel could be sufficiently suppressed and effective could be confirmed to the stabilization of magnetic levitation when the steel plate was transported.
