Abstract:This paper is concerned with the problem of H-infinity fuzzy filtering design with immeasurable premise variables for nonlinear systems presented as T-S model. First, the time derivatives of the membership functions are discussed and some linear matrices inequalities (LMIs) are obtained to bound it. Then, a new non-quadratic Lyapunov function which has the diagonal form is constructed to get some LMIs to design the filtering. In the end, two numerical examples are given to show that better H. performance can be obtained by the method in this paper than others in the literature. (C) 2015 Elsevier B.V. All rights reserved.
