| Research Abstract |
In the transport system of a thin-steel-plate production line, there is a problem that the quality of the plate surface deteriorates over time because the plate is usually in contact with rollers. To solve this problem, studies of electromagnetic levitation technology have been carried out. However, when a flexible thin steel plate with a thickness of less than 0.3 mm is targeted for levitation, levitation control becomes difficult because the thin plate undergoes increased flexure. We propose the levitation of a flexible thin steel plate that is bent to an extent that does not induce plastic deformation. In this study, we examine the levitation performance of a thin steel plate using sliding mode control. The obtained results were compared with the optimal control results. As a result, it was verified that the suppressive effect of the sliding mode control on disturbance is sufficient.
