Recently, research on a conveyance system by magnetic levitation of steel plates has been active. Since the design of its control system is generally carried out for a linearized model, it is difficult to secure satisfactory robustness in the control system. This is because nonlinearity (which is ignored in modeling) and several disturbances exist in reality. In addition, for an actual steel plate conveyance process it will be necessary to develop a control system that takes into consideration various parameter errors, such as nonuniformity of the plate thickness and the associated weight variation. In this paper, we examine the achievement of robustness in the control system using μ-synthesis. Uncertainties in the noncontact electromagnetic support system of steel plates are considered.
