Modeling and control for a magnetic suspension system. - 49 p.

Thesis (M.S.Eng.)--University of Massachusetts Lowell, 2008.

This thesis investigates some modeling and control problems for a magnetic suspension lest rig. The control objective is to bring the gap between the suspended beam and the electromagnet to a given reference value as soon as possible and keep it there In the presence of an uncertain load. A crucial problem of the experiment is to identify the property of the electromagnet. An experimental method is designed to identify three key parameters for an approximate model for the electromagnet. Based on the approximate model, three approaches are presented for designing controllers to achieve robust tracking. Experimental results show that the Lyapunov approach, which directly takes into account the uncertain nonlinearity and the constraints, is most effective. Through the controlled dynamic responses from the experimental data, the uncertain nonlinear model of the electromagnet is validated and further refined by comparing the acceleration of the motion from digital differentiation and that from the model. It is expected that the modeling and control design methods developed in this study can be extended to general magnetic suspension systems.
