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…
Global Stability Results for Systems Under Sampled-Data Control
Iasson Karafyllis, Costas Kravaris
In this work sufficient conditions expressed by means of single and vector Lyapunov functions of Uniform Input-to-Output Stability (UIOS) and Uniform Input-to-State Stability (UISS…
Stability Results for Systems Described by Retarded Functional Differential Equations
Iasson Karafyllis, Pierdomenico Pepe, Zhong-Ping Jiang
In this work characterizations of notions of output stability for uncertain time-varying systems described by retarded functional differential equations are provided. Particularly,…
A Small-Gain Theorem for a Wide Class of Feedback Systems with Control Applications
Iasson Karafyllis, Zhong-Ping Jiang
A Small-Gain Theorem, which can be applied to a wide class of systems that includes systems satisfying the weak semigroup property, is presented in the present work. The result gen…
