Stability Analysis by a Nonlinear Upper Bound on the Derivative of Lyapunov Function
(Elsevier Ltd., 2020) Şahan, Gökhan
In this work, we give results for asymptotic stability of nonlinear time varying systems using Lyapunov-like Functions with indefinite derivative. We put a nonlinear upper bound for the derivation of the Lyapunov Function and relate the asymptotic stability conditions with the coefficients of the terms of this bound. We also present a useful expression for a commonly used integral and this connects the stability problem and Lyapunov Method with the convergency of a series generated by coefficients of upper bound. This generalizes many works in the literature. Numerical examples demonstrate the efficiency of the given approach. © 2020 European Control Association

Predictor-Based Robust Control of Uncertain Nonlinear Systems Subject To Input Delay
(Elsevier Ltd., 2012) Obuz, Serhat; Tatlıcıoğlu, Enver; Çekiç, Sadettin Ç.; Dawson, Darren M.
In this paper, a tracking controller is developed for a class of nonlinear systems subject to time delay in the control input, uncertainties in the dynamic model, and additive disturbances. The control development is based on a novel predictor-like method to address the time delay in the control input. Lyapunov based stability analysis is used to prove semi-global asymptotic tracking. © 2012 IFAC.
