A Note on Sampled-Data Observers
Iasson Karafyllis, Tarek Ahmed-Ali, Fouad Giri
We present a new approach for deriving sampled-data observers from continuous-time observers that feature an Input-to-Output Stability property with respect to the output measureme…
Stability Results for the Continuity Equation
Iasson Karafyllis, Miroslav Krstic
We provide a thorough study of stability of the 1-D continuity equation, which models many physical conservation laws. In our system-theoretic perspective, the velocity is consider…
Sampled-Data Observers for Delay Systems and Hyperbolic PDE-ODE Loops
Tarek Ahmed-Ali, Iasson Karafyllis, Fouad Giri
This paper studies the problem of designing sampled-data observers and observer-based, sampled-data, output feedback stabilizers for systems with both discrete and distributed, sta…
Sampled-Data Control of the Stefan System
Shumon Koga, Iasson Karafyllis, Miroslav Krstic
This paper presents results for the sampled-data boundary feedback control to the Stefan problem. The Stefan problem represents a liquid-solid phase change phenomenon which describ…
Lyapunov-Based Boundary Feedback Design For Parabolic PDEs
Iasson Karafyllis
This paper presents a methodology for the construction of simple Control Lyapunov Functionals (CLFs) for boundary controlled parabolic Partial Differential Equations (PDEs). The pr…
Global Stabilization of a Class of Nonlinear Reaction-Diffusion PDEs by Boundary Feedback
Iasson Karafyllis, Miroslav Krstic
This paper provides global exponential stabilization results by means of boundary feedback control for 1-D nonlinear unstable reaction-diffusion Partial Differential Equations (PDE…
