- Abstract:
- The filtering problem of networked control system with time-varying delay is studied, and an H∞ filter is designed to keep the time-varying delay system stable. Based on the Delta operator, the design method of continuous domain can be directly applied to the design of discrete domain. Firstly, the network control system with time-varying delay is modeled, and the filter error system is constructed. Then, the useful time delay item that is often neglected is retained by using the Lyapunov-Krasovskii functional method, and the H∞ filter of the network control system The performance analysis of the error system is carried out, and then a sufficient condition for making the filtering error system asymptotically stable is given through a set of linear matrix inequalities, and the design method and derivative expression of the H∞ filter are obtained. Finally, the method is shown by a numerical example. validity.
