Abstract
This paper deals with a design problem of a robust controller with adjustable parameters for a class of uncertain nonlinear systems. The proposed robust controller is composed of a state feedback with a LQ optimal gain matrix derived by using the nominal system and adjustable parameters. In this paper, we show that sufficient conditions for the existence of the proposed robust controller are given in terms of LMIs. Finally, numerical examples are presented.
