New results on delay-dependent robust stability criteria of uncertain fuzzy systems with state and input delays
This paper focuses on the delay-dependent stability analysis and stabilization for uncertain T-S fuzzy control systems with state and input delays. The key features of the approach include the introduction of uncorrelated augmented matrix items into the Lyapunov functional and the use of a tighter bounding technology. In fact, these techniques lead to more general and less conservative stability conditions that guarantee a wide stability region. Our delay-dependent stability conditions thus obtained are given in terms of linear matrix inequalities (LMIs). Finally, some examples are included to show that the proposed criteria improve the existing results significantly. (C) 2008 Published by Elsevier Inc.
