H-infinity filter design for discrete-time networked systems with random communication delays
具有随机通讯时延的离散网络化系统的H∞滤波器设计

The sensors and filter are connected via a limited bandwidth communication channel.The system measure- ments are often subject to randomly varying communication delays.A H-infinity filtering problem is proposed for linear discrete-time networked systems with random communication delays.The problem addressed here is the design of a linear H-infinity filter such that the error systems are exponentially mean-square stable and guarantee a prescribed H-infinity per- formance in term of linear matrix inequality(LMI).The filter is then obtained by solving a LMI using convex optimization techniques.A numerical example is also provided to demonstrate the validity of the proposed design approach.
