“…During the past two decades, the guaranteed cost control problem for a two-dimensional (2-D) discrete system has drawn the attention of many researchers (see Dhawan and Kar, 2007, 2011; Hien and Trinh, 2017; Tandon and Dhawan, 2016; Xu and Yu, 2009; Ye et al, 2011, and the references cited therein for a sample of the literature) due to its extensive application in controlling a real plant. The aim of guaranteed cost control is to design a controller such that the resulting closed-loop system is asymptotically stable and an upper bound on the closed-loop cost function is guaranteed.…”
