Summary

Develops a five-degree-of-freedom state-space model for the sled dynamics of a passively levitated electrodynamic maglev system. The model connects coil-magnet geometry and flux-current-force interactions to a parameterized form that is useful for system identification and later robust feedback-control design.

Abstract

A model that describes the 5-DOF dynamics of a passively levitated electrodynamic Maglev system is presented. The model is based on the flux-current-force interactions and the geometric relationships between the levitation coils and the permanent magnets on the sled. The model is presented in a parametric state-space formulation, suitable to extract model parameters from input-output measurements in a minimum mean-square error sense. The proposed structure is very well suited for parameter estimation and to later develop robust feedback control of the sled dynamics.
