A test for stability robustness of linear time-varying systems utilizing the linear time-invariant v-gap metric

Griggs, Wynita; Lanzon, Alexander; Anderson, Brian


A stability robustness test is developed for internally stable, nominal, linear time-invariant (LTI) feedback systems subject to structured, linear time-varying uncertainty. There exists (in the literature) a necessary and sufficient structured small gain condition that determines robust stability in such cases. In this paper, the structured small gain theorem is utilized to formulate a (sufficient) stability robustness condition in a scaled LTI νν-gap; metric framework. The scaled LTI νν-gap;...[Show more]
