| description | This paper is concerned with the robust non-fragile filtering for a class of networked systems
with distributed variable delays. We model such a complex delay system with an augmented switched
system. For the filtering implementation uncertainty, a stochastic variable is employed to indicate random
occurrence of the filter gain change, and a norm bound to measure the change size. The suitably weighted
measurements are proposed for filter performance improvement, instead of direct use of the measurements
themselves which may have significant delays and degrade the performance. With some improved stability
and l2 gain analysis for the switched systems, a new sufficient condition is obtained such that the filtering
error system is exponentially stable in the mean square sense and achieves a prescribed H∞ performance
level. A numerical example is given to show the effectiveness of the proposed design. |
