This paper describes model identification of an active magnetic levitation laboratory process. Magnetic levitation is a nonlinear, open-loop unstable and time-varying dynamical system whose modelling and control are difficult. Theoretical model takes into account set of parameters which are difficult to identify. The proposed approach assumes discrete-time form of the model the parameters of which are tuned using nonlinear optimisation methods. The obtained model is more accurate and can be directly used in model-based control algorithms. Results of real experiment are demonstrated for the INTECO MLS2EM laboratory set-up.
