Feedback Stabilization Methods for the Numerical Solution of Systems of Ordinary Differential Equations
Iasson Karafyllis, Lars Grune
In this work we study the problem of step size selection for numerical schemes, which guarantees that the numerical solution presents the same qualitative behavior as the original…
Relaxed Lyapunov Criteria for Robust Global Stabilization of Nonlinear Systems
Iasson Karafyllis, Costas Kravaris, Nicolas Kalogerakis
The notion of the relaxed Robust Control Lyapunov Function (relaxed RCLF) is introduced and is exploited for the design of robust feedback stabilizers for nonlinear systems. Partic…
Global Stabilization by Means of Discrete-Delay Output Feedback
Iasson Karafyllis
In the present work, sufficient conditions for global stabilization of nonlinear uncertain systems by means of discrete-delay static output feedback are presented. Illustrating exa…
From Continuous-Time Design to Sampled-Data Design of Nonlinear Observers
Iasson Karafyllis, Costas Kravaris
In this work, a sampled-data nonlinear observer is designed using a continuous-time design coupled with an inter-sample output predictor. The proposed sampled-data observer is a hy…
Necessary and Sufficient Lyapunov-Like Conditions for Robust Nonlinear Stabilization
Iasson Karafyllis, Zhong-Ping Jiang
In this work, we propose a methodology for the expression of necessary and sufficient Lyapunov-like conditions for the existence of stabilizing feedback laws. The methodology is an…
