Abstract

This paper deals with modeling, uncertainty description and robustness analysis of a magnetic suspension system. First we derive a nominal model of the plant and consider its uncertainties e.g., linearization error, parametric uncertainties, and neglected dynamics. Then we set the interconnection structure which includes the above structurally represented uncertainties. Next the analysis of robust stability/performance for the obtained interconnection structure with three-types controllers by mixed structured singular value (mixed μ). Finally we evaluate the robustness of the proposed models and analytic results by experiments.
