Abstract :
A new lower bound is derived for the level of performance achieved by a given feedback compensator with a plant that is not known completely. The bound involves quantities reflecting the performance of the controller with a nominal model of the plant, quantities that can be computed from a finite number of frequency response samples of the unknown plant, and quantities related to the complexity (in the sense of Vinnicombe) of all systems involved.
