Design of a discrete tracking controller for a magnetic levitation system: A nonlinear rational model approach

© 2015 Fernando Gómez-Salas et al. This work proposes a discrete-time nonlinear rational approximate model for the unstable magnetic levitation system. Based on this model and as an application of the input-output linearization technique, a discrete-time tracking control design will be derived using the corresponding classical state space representation of the model. A simulation example illustrates the efficiency of the proposed methodology
