In this paper, we consider an analysis and design method for the robust controller of magnetic levitation systems with parameter perturbations. First, an expression of the uncertain plant is given by taking account of the physical parameter variations directly. Then, based on this result, an analysis/design method for robust controller is given in the framework of μ, where the unmodeled dynamics and the sensitivity performance are also taken into consideration. Second, the effectiveness of the proposed method is evaluated by experiments.
