On the Existence of Almost Periodic Solutions with Applications to Global Entrainment
Iasson Karafyllis, Miroslav Krstic
This paper provides two results that are useful in the study of the existence and the stability properties of almost periodic solutions for a given dynamical system. The obtained r…
Beyond Nonlinear Small-Gain Design: DADS with Partial-State Feedback
Iasson Karafyllis, Miroslav Krstic
Eduardo Sontag and coauthors studied Input-to-Output Stability (IOS) and the output asymptotic gain property. These notions changed control theory and recently had an impact on rob…
Lotka-Sharpe Neural Operators for Control of Population PDEs
Miroslav Krstic, Iasson Karafyllis, Luke Bhan +1
Age-structured predator-prey integro-partial differential equations provide models of interacting populations in ecology, epidemiology, and biotechnology. A key challenge in feedba…
Global Stability Analysis of the Age-Structured Chemostat With Substrate Dynamics
Iasson Karafyllis, Dionysios Theodosis, Miroslav Krstic
In this paper we study the stability properties of the equilibrium point for an age-structured chemostat model with renewal boundary condition and coupled substrate dynamics under…
Stabilization of Predator-Prey Age-Structured Hyperbolic PDE when Harvesting both Species is Inevitable
Carina Veil, Miroslav KrstiÄ, Iasson Karafyllis +2
Populations do not only interact over time but also age over time. It is therefore common to model them as age-structured PDEs, where age is the space variable. Since the models al…
On the Existence of Periodic Solutions with Applications to Extremum-Seeking
Iasson Karafyllis, Miroslav Krstic
This paper provides two results that are useful in the study of the existence and the stability properties of a periodic solution for a given dynamical system. The first result dea…
