Control of Magnetic Levitation System suspended by Elastic Element

Abstract

We introduce a control method of a magnetic levitation system (Maglev) suspended by an elastic element. A Maglev conveyance system has the merits of high efficiency and maintenance-free. Usually, the guide rail of the Maglev conveyance system is considered as a rigid structure, and its deformation and vibration are ignored. To reduce the weight and cost of the guide rail, we investigate a control method in the case of the flexible guide rail. In this paper, a one-degree-of-freedom Maglev system suspended by leaf spring is experimentally studied and stable levitation is achieved. The experimental device and the results of the levitation tests are shown.
