Abstract: In this paper, we study the problem of robust H∞-control design for a class of nonlinear systems with parameter uncertainty by means of Hamilton-Jaeobi inequality. We obtain the sufficient conditions for the existence of static state feedback controller and dynamic output feedback controller under which the closed-loop systems have robust H∞-performance, respectively. Furthermore, we develop the design for robust controllers.-
