In the factory, the continuous steel plates subjected to iron and steel processes are supported by a series of rollers during processes such as rolling. However, because roller comes in contact with the steel plates, the problem of surface quality deterioration arises. To solve this problem, we develop a non-contact guide for parts of the steel plate at which its traveling direction changes in high-speed traveling by applying an electromagnetic force from the direction of the edge of the steel plate, and experimentally examine the effectiveness of the system. Moreover, when the position of the plate is controlled, it is extremely difficult to determine the mass of the control target. We confirm the suppressive effect of a sliding mode control theory that has robustness in mass variation. The results indicate that the proposed system can be achieved.
