In this paper, the problem of robust filter design based on network is investigated. Using Lyapunov-Krasovskii functional and free-weighting matrix approach, the criteria for robust H ∞ performance analysis of the filtering-error systems are proposed by reserving all terms in the derivative of Lyapunov-Krasovskii functional and dealing with the different parts of uncertainties of the sestems separately. Based on the derived criteria, the design method of robust H ∞ filter is obtained in term of linear matrix inequalities(LMIs). A numerical example is given to demonstrate the validity and the less conservativeness over the existing methods.
