A robust redesign for stabilization of a class of uncertain nonlinear systems

摘要

In this paper, a state feedback control is proposed for stabilization of strict feedback systems with one matched and unmatched uncertainties. Closed loop system stability is proved using Lyapunov stability and singular perturbation theories. In overcoming the uncertainties we used high gain filters which are designed based on the time scale separation technique. The control design procedure is illustrated by applying it to a sample system and the simulation results are shown.
