That is\, the problem of determining if two s ystems interconnected via feedback will be stable. In the case of linear t ime-invariant systems\, under mild conditions the solvability of a set of linear matrix inequalities (LMIs) is a both necessary and sufficient condi tion for stability. Nevertheless\, models of reality are always imperfect\ , and in robust stability analysis one therefore instead consider the prob lem if a feedback interconnection between a nominal system and a set of un certainties is stable for all uncertainties in the set. In this talk\, I w ill present new results on that robustness to certain forms of structured uncertainties is equivalent with the existence of certain forms of structu red solutions to the LMIs. The talk is aimed to be self-contained\; no pri or knowledge on control theory is needed\, and all relevant concepts will be introduced and explained.\n LOCATION:https://researchseminars.org/talk/cam/25/ END:VEVENT END:VCALENDAR
