Ws. Kafri et Eh. Abed, STABILITY ANALYSIS OF DISCRETE-TIME SINGULARLY PERTURBED SYSTEMS, IEEE transactions on circuits and systems. 1, Fundamental theory andapplications, 43(10), 1996, pp. 848-850
Stability results for discrete-time singularly perturbed systems are o
btained under less severe assumptions than in previous work. Exact upp
er bounds on the singular perturbation parameter ensuring system stabi
lity are obtained in the course of the analysis.
