Fragility analysis for CWEAS state feedback control

The research explores the robustness of closed-loop CWEAS (componentwise exponential asymptotic stability) with respect to plant and/or controller uncertainties. The main focus is placed on the fragility/nonfragility analysis that quantifies the controller contribution to the closed-loop robustness. We develop a computer-assisted methodology for testing CWEAS robustness, which is illustrated by a relevant case study. The lack of similar studies in the literature field does not allow direct comparisons with other approaches.
