Scaled Graph Containment for Feedback Stability: Soft-Hard Equivalence and Conic Regions
Eder Baron-Prada, Julius P. J. Krebbekx, Adolfo Anta +1
Scaled graphs (SGs) offer a geometric framework for feedback stability analysis. This paper develops containment conditions for SGs within multiplier-defined regions, addressing bo…

Mixed Small Gain and Phase Theorem: A new view using Scale Relative Graphs
Eder Baron-Prada, Adolfo Anta, Alberto Padoan +1
We introduce a novel approach to feedback stability analysis for linear time-invariant (LTI) systems, overcoming the limitations of the sectoriality assumption in the small phase t…
