Feedback H_∞ Filtering For A Class Of Uncertain Linear Systems With Time-varying Delay

In the past years,the research of stability of the linear uncertain systems have obtain many remarkable results,many literatures focus on H_∞filtering of linear time-delay uncertain systems.In this paper,delay-dependent H_∞filtering problems are discussed. For Robust H_∞filtering problems,assuming that the time-varing delay is continuous uniformly bounded,based on a new integral inequality,some new delay-dependent conditions for the esistence of a suitable H_∞filter are derived,which guarantee that filtering error systems is asymptotically stable with a prescribed level of H_∞noise attention.
