| 摘 要： | The nonfragile H_∞filtering problem affected by finite word length (FWL) for linear discrete-time systems is investigated in this paper.The filter to be designed is assumed to be with additive gain variations,which reflect the FWL effects on filter implementation.A notion of structured vertex separator is proposed to deal with the problem and exploited to develop sufficient conditions for the nonfragile H_∞filter design in terms of a set of linear matrix inequalities (LMIs).The design renders the augmented system asymptotically stable and guarantees the H_∞attenuation level less than a prescribed level.A numerical example is given to illustrate the effect of the proposed method.
