Rate My Professor Felix Schwenniger

Schwenninger's research focuses on functional analysis, particularly operator theory, with applications to the analysis and control of partial differential equations in infinite-dimensional systems. His interests include semigroup theory, functional calculus, input-to-state stability of infinite-dimensional systems, funnel control, optimization of constants, and Crouzeix's conjecture. He has produced 78 research outputs, including publications in leading journals such as SIAM Journal on Control and Optimization, Journal of Differential Equations, Automatica, and Systems & Control Letters. Among his most cited works are "Infinite-dimensional input-to-state stability and Orlicz spaces" (2018, with B. Jacob, R. Nabiullin, J.R. Partington; 135 citations), "On continuity of solutions for parabolic control systems and input-to-state stability" (2019, with B. Jacob, H. Zwart; 73 citations), "Input-to-state stability for parabolic boundary control: linear and semilinear systems" (2020; 62 citations), and "Funnel control for a moving water tank" (2022, with T. Berger, M. Puche; 55 citations). Schwenninger's scholarship has garnered over 737 citations according to Google Scholar. He serves as Associate Editor for Optimal Control Applications and Methods since 2021 and is scheduled as a plenary speaker at IWOTA 2026.
