Abstract

In this paper, we give a simple necessary and sufficient condition for asymptotic stability of linear parameter-varying difference systems with nonnegative matrix coefficients. Then, the complex, real, and positive stability radii of the difference systems are studied. The results also include recent results on positive homogeneous difference equations and positive delay discrete systems as special cases. Finally, a simple example is given to illustrate the obtained results.
