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…
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…
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…
The Age-Structured Chemostat with Substrate Dynamics as a Control System
Iasson Karafyllis, Dionysis Theodosis, Miroslav Krstic
In this work we study an age-structured chemostat model with a renewal boundary condition and a coupled substrate equation. The model is nonlinear and consists of a hyperbolic part…
DADS Under Unknown Input Coefficients
Iasson Karafyllis, Miroslav Krstic
This short note shows that the Deadzone-Adapted Disturbance Suppression (DADS) adaptive control scheme is applicable to systems with unknown input coefficients. We study time-invar…
