Abstract :
This work deals with the modeling and control of a magnetic levitation system. A nonlinear model, valid for a certain region of interest, is obtained by considering the compensation of the gravity force. A control strategy is designed for the system based on the concept of passivity, in particular by establishing the equivalence of the levitation system to a passive one and considering a position regulation strategy. Real time experiments were carried out to show the performance of the proposed control scheme
