摘要

This paper focuses on the problem of H-infinity filtering for continuous-time T-S fuzzy nonlinear quadratic systems with a varying time delay. To ensure H-infinity performance bound for the augmented nonlinear quadratic system constituted by the original system and the filter, we use a quadratic Lyapunov-Krasovskii functional and some inequality conditions. We aim to derive a less conservative result than the existing ones by designing the filter parameters via linear matrix inequalities. Free parameters provide extra degrees of freedom in optimizing the guaranteed H-infinity performance and lead to a less conservative design.
