Robust non-fragile controllers for uncertain linear continuous-time systems

Abstract

This paper deals with a design problem of robust non-fragile controllers for linear continuous-time systems with uncertainties which are included in both the system matrix and the input one. In this paper, we deal with two classes of control gain perturbations and show that sufficient conditions for the existence of the robust non-fragile controller are given in terms of linear matrix inequalities (LMIs). Finally, illustrative examples are presented.
