The problem of robust stabilization of a class of dynamical systems with partial knowledge of uncertainty bounds is considered. Here, the coefficient vector which fix the bounds of the uncertainties is assumed to be unknown. By combining a conventional robust state feedback controller with the proposed adaptive law which is used to update the bounds, we construct a new robust state feedback controller which can guarantee uniform ultimate boundedness of the resulting uncertain closed-loop systems. Furthermore, we apply it to river pollution control systems and show the validity of the adaptive robust controller proposed in this paper.
