Abstract :
The purpose of this paper is to broaden the scope of integral-quadratic-constraint based structured robustness analysis in a way that accommodates feedback interconnections of unstable linear time-invariant systems. This is achieved by exploring the use of Vinnicombe¿s v-gap metric as a measure of distance. Various standard robustness analysis problems are revisited within the context of the main result.
