Abstract
For thin steel plates which are used in many industrial products including those of the automobile industry, we have proposed a magnetic levitation control system and confirmed its realization by means of the digital control experiment. However, in the case in which only the levitation control is applied to the steel plate, it has no horizontal restraining force on the direction of travel. Therefore electromagnetic actuators are installed in order to control the horizontal position movement of the levitated sheet steel. The electromagnetic attractive control forces of the actuators are given for the two facing edges of the levitated sheet steel, from the horizontal direction. In this paper, the suppression effect of elastic vibration of steel beam in the under electromagnetic field is reported.
