Abstract

This paper considers the position tracking problem of a magnetic levitation system in the presence of modelling errors due to uncertainties of physical parameters. A robust nonlinear controller is designed to achieve excellent position tracking performance. The recently developed dynamic surface control is modified and applied to the system under study, to overcome the problem of “explosion of terms” associated with the backstepping design procedure. Input-to-state stable property of the control system is analyzed, and experiment results are included to show the excellent position tracking performance of the designed control system.
