Noncontact vibration control of a magnetic levitated rectangular thin steel plate was studied experimentally. We fabricated equipment which enables the generation of elastic vibration via forced input of disturbance to a levitated thin steel plate, so that the suppressive effect on the elastic vibration could be examined. Two models of the steel plate, a single-degree-of-freedom model and a continuous model, were considered in this study. By applying the optimal control theory to the each model, the superiority of the models with respect to the suppressive effect of elastic vibration was examined. Furthermore, suboptimal control was applied in which spillover of elastic vibration was considered, the experimental results obtained using the optimal control and the suboptimal control were compared, and the applicability of these controllers was discussed.
