Non-Uniform in Time State Estimation of Dynamical Systems
Iasson Karafyllis, Costas Kravaris
In this paper it is showed that if a time-varying uncertain system is robustly completely detectable then there exists an estimator for this system, i.e. we can estimate asymptotic…

Non-Uniform in Time Robust Global Asymptotic Output Stability for Discrete-Time Systems
Iasson Karafyllis
In this paper the notions of non-uniform in time Robust Blobal Asymptotic Output Stability (RGAOS) and Input-to-Output Stability (IOS) for discrete-time systems are studied. Charac…
