This paper is conced with the problems of H-two filtering for discrete-rime Markovian jump linear systems subject to logarithmic quantization.We assume that only the output of the system is available,and therefore the mode information is nonaccessible.In this paper,a mode-independent quantized H-two filter is designed such that filter error system is stochastically stable.To this end,sufficient conditions for the existence of an upper bound of H-two norm are presented in terms of linear matrix inequalities.Considering uncertainty of system matrices,a robust H-two filter is designed.The proposed method is also applicable to cover the case where the transition probability matrix is not exactly known but belongs to a given polytope.Finally,numerical examples are provided to demonstrate the effectiveness of the proposed approach.
