Abstract

Based on a piecewise Lyapunov-Krasovskii functional (PLKF), this paper presents an H"~ piecewise filtering method for T-S fuzzy systems with time delays. It is shown that the H"~ filtering performance can be satisfied if there exists a PLKF. The PLKF and the corresponding filter can be obtained by solving a set of linear matrix inequalities (LMIs). Two examples are presented to demonstrate the efficiency and advantage of the proposed method.
