On the stabilizability of imperfectly known nonlinear delay systems of the neutral type

This investigation addresses the problem of stabilizing a class of imperfectly known nonlinear neutral-type time-delay systems. Invoking delay independent stability criteria and a deterministic methodology based on Lyapunov-Krasovskii functionals, a class of stabilizing controls is designed to ensure global uniform asymptotic stability of the zero state for the prescribed class of systems. An application of the results to a specific sub-class is provided with a simulation example included to illustrate the practical applicability.
