Abstract: We have developed a noncontact guide system for a high-speed travelling elastic steel plate in which electromagnetic forces are given at the edges of the plate by actuators for position control of the plate. In position control of the endless plates, it is extremely difficult to determine the mass of the control target. We study how the suppressive effect of the sliding mode control theory gives robustness in mass variation. In applying the sliding mode control theory, it is necessary to get quick response of the current control of the actuator in order to get the matching condition. With the help of the current feedback, the coil inductance of the actuators is forced to become almost zero.
