In this paper we propose an adaptive observer to solve this problem for a class of unknown variable time-delay nonlinear systems where the state matrix depends on the input persistency excitation. To achieve this we combine the use of a Kalman-like observer with a suitable choice for the Lyapunov-Krasovskii functional. This is done under a sufficient number of hypothesis to guarantee the convergence of the observer inside a sphere depending of the delay upper bound. The proposed strategy is tested in simulation by considering a mixed piece-wise and sinusoid time delay function and its efficiency when the problem of persistency excitation occurs.Lire moins >
