Networked filtering for singular systems with unreliable channels

This paper concerns a robust H_∞ filtering problem for uncertain discrete-time singular systems with possible missing measurements due to unreliable networked transmission channels. The stochastic variable satisfying Bernoulli random binary distribution is introduced to model the missing phenomena. The corresponding delay filtering error dynamics is induced. We provide a set of sufficient conditions for the existence of the desired filter, and propose a robust filter design method under the linear matrix inequality framework. A numerical example is given to illustrate the effectiveness of the proposed method.
