摘要

This article investigates the stability/stabilization problem for Takagi-Sugeno (T-S) descriptor systems with time-varying delay. A transformation-based model has been employed through a two-term approximation, and the input-output approach has been investigated using the small gain Theorem. A novel free-weighting matrix method, in combination with a new construct Lyapunov-Krasovskii functional (LKF), has been developed. Delay-dependent conditions have been obtained in a set of linear matrix inequalities (LMIs). To estimate the system states T-S fuzzy descriptor observer-based controller has been introduced. The gains have been designed using a new design strategy. Finally, three examples have been borrowed to test the merit and the validity of the proposed method.
