Recently, magnetic levitation technology that is capable of gripping and conveying objects in a non-contact manner has attracted attention, and active studies that use the characteristics of magnetic force, such as the electromagnetic suspension and induction repulsion methods, have been performed [

With various industrial demands, the surface quality of steel plates continues to be enhanced. However, since a contact conveyance using rollers is mainly adopted in the process of a thin-steel-plate production line, the problem of surface quality deterioration still remains. It is expected that magnetic levitation technology can be applied to thin steel plate production processes, which require high surface quality. However, elastic vibration is induced because of the flexibility arising from the plate thickness and area; therefore, the stability at the time of levitation is significantly impaired. Prior research has indicated the size of the objective steel plate to be relatively small, and no successful report has been made on a stable noncontact conveyance system of a very thin steel plate, despite the increasing demand in the recent years [

In the past, our research group has constructed an electromagnetic levitation control system in which the relative distance between the electromagnet and a steel plate was maintained, aimed to prevent the steel plate from falling from the conveyor or contacting the electromagnet during electromagnetic levitation conveyance. Furthermore, we have proposed a method of levitating a thin steel plate with a thickness of less than 0.3 mm by moderately bending it beforehand [

The levitation stability was improved by bending and this subsequent stability was maintained through the input of external disturbances, such as control current or vibrating the frame where the electromagnet unit was installed [
