Abstract
Robust control design for a class of nonlinear system and online estimation of uncertainty is presented. Estimation is done via high gain observers, and the estimates are used by the proposed robust control to relax prior knowledge, required in a typical robust control design on the size of uncertainties, without assuming a bounding function, the proposed control scheme has the potential to being less conservative while guaranteeing robust stability.
