Abstract :
We consider the stability robustness problem for nominally stable linear discrete-time systems. Using time-domain analysis methods and Lyapunov theory, bounds on the norms of time-varying (non)linear perturbations are given to maintain the asymptotic stability of these systems in the presence of such perturbations.
