Abstract

This paper proposes a new delay-dependent stability condition for uncertain time-delay systems, which is simple yet not as conservative as previous ones in the literature. The proposed condition, which is formulated in terms of linear matrix inequalities, does not employ any model transformation and therefore is free from the conservatism due to model transformations. Numerical examples are presented to show the usefulness of the proposed condition.
