title = "Upper and lower bounds for approximation in the gap metric",
abstract = "The authors establish upper and lower bounds for the closest approximant of degree k < n in the gap metric to a plant of degree n. The bounds are expressed in terms of the singular values of two Hankel operators defined from the symbol of the graph of the plant. The question of robust stability and performance of feedback systems is examined in the context of approximation of plant and controller in the gap metric.",
