Abstract :
In many data fusion systems, process noise and/or measurement noise may have unknown statistics characteristics but limited power. These problems may be addressed by considering a H∞ fusion-filtering problem. In this paper we obtain a characterization of all H∞ fusion filters based on DAREs and LMIs, respectively. Also, a numerical example is presented to illustrate the performance of H∞ fusion filter.
