Guaranteed cost control of T-S fuzzy systems with state and input delays

This paper focuses on the problem of guaranteed cost control for T-S fuzzy systems with state and input delays. Stability and stabilization conditions are first proposed, which are delay-dependent for state delay and delay-independent for input delay. Further, the guaranteed cost problem is addressed. All the results are presented in terms of linear matrix inequalities (LMIs). Some examples are used to illustrate the effectiveness and feasibility of the approaches proposed in this paper.
