“…Delay is often present due to limited speed of information processing and data transmission among different parts of a physical system (Changchun et al, 2009;Dolocan, 1978;Li and Gao, 2011;Nyongesa et al, 2001;Perrott and Cohen, 1996;Tranter et al, 2007;Zhu et al, 2010). A wide range of problems concerning 2D systems incorporating a delay can be found in the literature (Benhayoun et al, 2010(Benhayoun et al, , 2013Benzouia et al, 2011;Chen, 2010aChen, , 2010bDey and Kar, 2014;Kandanvli and Kar, 2009aXu and Yu, 2009a). The stability conditions of digital filters with state delay have been derived (Ahn, 2013(Ahn, , 2014a(Ahn, , 2015Chakrabarti and Mitra, 2003;Dey and Kar, 2014;Shyu et al, 2009;Kandanvli and Kar, 2009aMadanayake et al, 2014).…”
