In this paper, a method of electromagnetic levitation control of a thin steel rectangular plate (length : 800mm, width : 600mm, thickness : 0.3mm) with free edges is prerented. To carry out fundamental investigation of the restraint of elastic vibration of the plate, the steel plate is reinforced by plastic beams at two opposite edges. This plate is supported in a contactless manner by attractive forces of five electromagnetic actuators which are controlled by feedback signals from five gap sensors to stabilize the levitation behavior. The optimal control theory and the suboptimal control theory are applied in this study. To verify the usefulness of these methods, experiments in which the optimal digital control theory was applied were performed. As a result, it was confirmed that these control methods were very effective in levitating the plate, and it was further observed that the spillover of residual vibration modes was restrained by applying the suboptimal control method.
