“…In order to derive a less conservative stability criterion, several methods are utilized, such as transformation technique, 16 free weighting matrices technique, 17 integral/summation inequalities method, 18 delay-partitioning method, 19 and input-output approach combined with scaled small gain theorem. 20,21 In the past few years, many works have focused on the study of to the problem of delay-dependent stability for 2D systems with delays, to mention a few: in the work of Yao et al, 22 the free-weighting matrices has been introduced to cope with the stability analysis of 2D state-delayed systems described by the FM second model. In the work of Hien and Trinh, 23 new 2D finite-sum inequalities have been proposed to deal with the problem of stability analysis of discrete-time 2D Roesser systems with interval time-varying delays.…”
