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). An example is presented to demonstrate the efficiency of the proposed method. l
