Hâˆ‍ Switched Filtering for Networked Systems Based on Delay Occurrence Probabilities1

Abstract

This paper considers the state estimation problem for discretetime systems in a network environment. Specifically, the networkinduced delay from the sensor node to the estimator node is modeled as a finite set of delays with corresponding occurrence probabilities. The design of Hâˆ‍ switched filters is proposed. The switching is performed according to the detected time delay. The occurrence probability of the delay is incorporated into the filter design, which can improve the filtering performance. Simulation studies and comparisons illustrate the effectiveness and the improvement of the proposed design method.
