Abstract: This paper highlights a broad investigation on system dynamics and its stability aspects of four different electromagnetic attraction type levitation prototypes. An exhaustive comparative study on levitation prototypes for a spherical object, two flat plates and a C-shaped plate has been discussed broadly. A spherical geometry has its advantages due to the axis symmetry whereas the plates have asymmetric symmetry. This geometry change brings a few significant challenges in design, modelling, controller design, fabrication and robustness of the setup. Thus the study will help to develop more complex prototypes for real life applications, e.g., MagLev (magnetic levitation) vehicle.

Keywords: electromagnetic levitation; lead compensator; window comparator; frequency analysis.
