For thin steel plates, which are used in many industrial products including those in the automobile industry, we have proposed a magnetic levitation control system and confirmed its realization by means a digital control experiment. However, when only levitation control is applied to the steel plate, there is no horizontal restraining force in the direction of travel. Therefore, electromagnetic actuators are installed to control the horizontal movement of the levitated sheet steel. The electromagnetic attractive control forces of the actuators are applied to the two facing edges of the levitated sheet steel, from the horizontal direction. In this study, the suppression of the bending the plate during the horizontal noncontact positioning control is reported.
