Generalized H-two filtering for networked systems with bandwidth constraints
带宽受限网络化系统的广义H2滤波

The generalized H-two filtering problem is studied for a class of networked systems with bandwidth constraints. The quantized measurement signal is used as the input of the filter. Then, by using the logarithm quantizer, we model the filter-error system as a time-delay system with norm-bounded uncertainty. Sufficient conditions are derived for the asymptotic stability of the filter-error system by the Lyapunov stability theory and the linear matrix inequality (LMI) technique; and the design procedures for the filter are also provided. A numerical example is provided to illustrate the feasibility of the proposed method.
