Abstract: This paper presents the elementary design, electromagnetic (EM) analysis, system modelling, controller design and fabrication of an electromagnetic levitation setup. The parameters are being evaluated by conventional analytical method and verified by experimental and FE-based results. The finite element (FE) model has been developed using standard software packages. Pohl's method is extended for the analytical results. The analytically evaluated results are verified with experimental results too. Controllers have been designed by classical control system methods. Parameter uncertainty and robustness issues have been considered carefully. Analogue controllers have been designed, analysed and implemented for the system. Their performances have been simulated and these are practically tested. Finally, the plate has been successfully levitated at an operating gap of 8 mm.
