State Time-delay Feedback Robust H_inf. Control for T–S Fuzzy Time-delay Systems with Parameter Uncertainties

Han-Liang Huang

Abstract


In this paper, we consider the problem of state time-delay feedback control for uncertain fuzzy systems with time-delay. The Takagi–Sugeno (T–S) fuzzy model is used to described such systems. Based on the Lyapunov functional approach, a design method of robust H_inf. controller is obtained. All the results are given in terms of linear matrix inequalities (LMIs). The effectiveness of our method is demonstrated by a numerical example.

Keywords


state time-delay feedback controller, T–S fuzzy systems, uncertainty, delay-independent.

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.
