Nonlinear simulink model of magnetic levitation laboratory plant

Abstract

The paper deals with modelling of a magnetic levitation laboratory plant. The goal of the work was to create a nonlinear model in a MATLAB/Simulink environment representing behaviour of a real-time CE152 laboratory plant. The CE152 is a magnetic levitation model developed by Humusoft company. From the control point of view, the CE152 magnetic levitation plant is a nonlinear very fast system. The model of the plant is developed using first principle modelling and subsequently made more precise using real-time experiments. The behaviour of the resulting Simulink model is compared with the behaviour real-time plant. The Simulink model can be further used in the process of controller design. © ECMS Thorsten Claus, Frank Herrmann, Michael Manitz, Oliver Rose (Editors).
