Abstract: When sheet steel travels at high speed in a processing facility, rollers are usually used as supporters. However, when rollers are used, deterioration caused by cracking is possible. The authors have proposed a magnetic levitation control system for sheet steel and confirmed the feasibility by an experiment on digital control. However, there is no horizontal restraining force in transport in the case of using only levitation control. Therefore, we proposed to install electromagnets in order to control the horizontal position. For the basic examinations, the sheet steel plate (length 800 mm, width 600 mm, thickness 0.3 mm) was reinforced by light carbon pipes in this study. To verify the usefulness of the proposed noncontact positioning control system of sheet steel, a digital control experiment was performed on transport. As a result, good positioning control performance for the levitated steel plate was obtained.
