A real-time nonlinear robust controller for magnetic levitation systems

This paper first introduces a nonlinear robust controller for maglev systems. This controller which employs mainly sliding mode concepts ensures global stability of the closed-loop system. A theorem has been established in the paper to prove the overall system stability. To show how good the proposed controller is we apply it to the maglev system. Furthermore, it has been shown that the proposed controller is robust against plant parameter uncertainties. The Experimental result clearly approves the effectiveness of the designed controller.
