Author_Institution :

Abstract :
A criterion for the global asymptotic stability of 2D discrete systems described by the Roesser model employing state saturation arithmetic is presented. A comparison of the present criterion with the previous criteria and an illustrative example showing the effectiveness of the present criterion are given.
