Distributed fusion robust H2 and H∞ filtering for uncertain discrete-time systems

The distributed fusion robust H₂ and H_∞ filtering problems for discrete-time systems with polytopic uncertainty are investigated. Based on the existing results on the robust H₂ and H_∞ filtering problems for single-sensor systems, the sufficient conditions for existing of distributed fusion robust H₂ and H_∞ filters are obtained. An illustrative example shows that the fusion filter is better than each local filter.
