New Stability Conditions for Switched Uncertain T-S fuzzy Systems with Two Additive Time Varying Delays

Fatima Ahmida, El Houssaine Tissir


This paper investigates the problem of stability robustness for continuous time Takagi-Sugeno (T-S) fuzzy switched systems with additive time varying delays. The approach is based on the Lyapunov–Krasovskii functional method and the use of Finsler’s lemma. The results are delay dependent and are expressed in term of LMIs. Numerical examples are provided to show the effectiveness of the present technique, compared to some recent results.


Switching system, additive time delays, linear matrix inequalities (LMIs); T-S fuzzy systems.

Disclaimer/Regarding indexing issue:

We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
