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…

Control Lyapunov Functions and Stabilization by Means of Continuous Time-Varying Feedback
Iasson Karafyllis, John Tsinias
For a general time-varying system, we prove that existence of an "Output Robust Control Lyapunov Function" implies existence of continuous time-varying feedback stabilizer, which g…
