Abstract

This paper is concerned with the filtering problem for networked systems with bounded measurement missing. A switched linear system model is proposed to describe the considered filtering error system. A sufficient condition is derived for the filtering error system to be exponentially stable and achieve a prescribed filtering performance level. The obtained condition establishes quantitative relations among the performance level and two parameters characterizing the measurement missing, namely, the measurement missing rate bound and the maximal number of consecutive measurement missing. A convex optimization problem is presented to design the linear filters. Finally, an illustrative example is given to show the effectiveness of the proposed results.
