Quantized H2 filtering for Markovian jump linear systems over networks with non-accessible mode information

This paper is concerned with the problems of quantized H₂ filtering for discrete-time Markovian jump linear systems over networks with non-accessible mode information. The quantizer considered here is logarithmic quantizer. In this paper, a linear time-invariant mode-independent quantized H₂ filter is designed such that filter error system is stochastically stable. Sufficient conditions for the existence of proposed filter is given in terms of linear matrix inequalities. A numerical example is provided to demonstrate the effectiveness of the proposed approach.
