Abstract
Most magnetic suspension systems used in industrial and research applications tend to have highly nonlinear dynamics with significant parametric and nonparametric uncertainties. In this paper, a linear H ∞ control law based on the mixed-sensitivity approach is developed for a magnetic suspension system possessing two degrees of freedom. A prototype suspension system was designed and constructed to provide a direct comparison between the actual and theoretical controller performances
