Abstract :
In this paper we consider the problem of disturbance suppression for a magnetic levitation system in presence of uncertainties on the physical parameters of the system. It is shown how a saturated feedback can be successfully used in order to solve the problem. The problem is cast as a nonlinear regulation problem in presence of input constraint and an internal model-based regulator is designed.
