  Thin steel plates are used in many industrial products, including those of the automobile industry. We propose a system of controlling the magnetic levitation and confirmed its realization by means of a digital control experiment. However, the use of a limited number of electromagnets cannot suppress static deflection or high-order-mode elastic vibration, which are characteristics of flexible magnetic materials. We therefore propose a hybrid system to control levitation of thin steel plates to solve this problem using the magnetic force generated by permanent magnets, which incur no operational costs. In this study, we attempted to determine the optimal gap, placement, and number of permanent magnets to reduce the deflection of thin steel plates under a generated magnetic field. The experiments on deflection were carried out on magnetically levitated thin steel plates to verify how useful the optimal placement of permanent magnets was.
