Abstract
A magnetic levitation apparatus is often employed in control education as a benchmark for the design of a control system for a nonlinear unstable process. In this paper we present a combined feedforward/feedback approach which takes into account the constraints of the system. In particular, we highlight the use of a feedforward control law which is based on a dynamic inversion of the closed-loop system. The robustness of the control system with respect to structured uncertainties is evaluated.
