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…
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…
Sufficient Conditions for String Stability
Iasson Karafyllis, Dionysis Theodosis, Markos Papageorgiou
Zhong-Ping Jiang devoted a large part of his work to the study of the stability properties of interconnected systems. In this short paper we celebrate Zhong-Ping Jiang's 60th birth…
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…
