A model that describes the 3-DOF dynamics of a passively levitated electro-dynamic maglevsystem is presented. The model is based on the flux-current-force interactions and the geometricrelationships between the levitation coils and the permanent magnets on the sled. The model ispresented in a parametric state-space formulation, suitable to extract model parameters frominput-output measurements in a minimum mean square error sense, and model predictions arecompared with measured trajectories in height, pitch and roll. The proposed structure is very wellsuited to later develop robust feedback control of the sled dynamics.
