This paper proposes a novel H\infty filtering technique for a class of discrete-time fuzzy systems. First, a novel kind of fuzzy H\infty filter, which is homogenous polynomially parameter dependent on membership functions with an arbitrary degree, is developed to guarantee the asymptotic stability and a prescribed H\infty performance of the filtering error system. Second, relaxed conditions for H\infty performance analysis are proposed by using a new fuzzy Lyapunov function and the Finsler lemma with homogenous polynomial matrix Lagrange multipliers. Then, based on a new kind of slack variable technique, relaxed linear matrix inequality-based H\infty filtering conditions are proposed. Finally, two numerical examples are provided to illustrate the effectiveness of the proposed approach. [ABSTRACT FROM AUTHOR]
