Switching control of H(infinity) gain scheduled controllers in uncertain nonlinear systems

Abstract

In this paper, we propose a switched H(infinity) gain scheduled controller for uncertain nonlinear systems with exogenous signals. Each controller is constructed at a distinct and fixed value of exogenous signals using H(infinity) synthesis methodology. Then the constructed controller set is switched according to the proposed switching scheme for the wide range of variation of exogenous signals. Moreover, it is shown that the switched control system guarantees stability during every switching. (C) 2000 Elsevier Science Ltd. All rights reserved.
