Abstract :
This paper presents an experimental realization of a current-controlled magnetic levitation system (MLS). MLS are nonlinear systems and are unstable in open loop, which makes the control aspect very challenging. It is therefore essential to design robust controllers to solve the problem. Nonetheless, as far as mathematical model and control design are concerned, current-controlled MLS are less complex than the conventional voltage-controlled systems widely discussed in literature. In this paper, a sliding mode regulator is experimentally implemented on a MLS. The nonlinear regulator is designed using the Matlab/Simulink and is run in real time using the RTW of Matlab. Experimental results show the effectiveness of the robust nonlinear controller
