Abstract: We design vortex control algorithms for electromagnet in a tracking problem. The main feature of these vortex algorithms is invariance property to unmatched external disturbances of the wide class. It is shown that the designed algorithms provide asymptotical convergence of output variables under influence of parametrical (unknown mass, active resistance of a coil, etc) and external disturbances. Simulation results show efficiency of the proposed procedure.

Keywords: magnetic levitation system, vortex algorithm, parametrical disturbances.
