Abstract

This paper tackles the H-infinity filtering problem for 2-D discrete stochastic systems. The approach is based on the Fornasini-Marchisini (FM) model. The objective is to propose a new design with sufficient condition via LMI formulations. Less conservative results are obtained by introducing additional free parameters by using the projection Lemma. This method provides extra degree of freedom in optimization of the H-infinity performance. The efficiency of the proposed approach is shown be several examples.
