Abstract: | This paper addresses the global output feedback regulation problem for a class of uncertain feedforward time-delay nonlinear systems. Unlike to the previous works, the nonlinear functions in the class of systems under consideration are dominated by an input-output function multiplied by an unknown parameter and linear unmeasured states. By using only one dynamic gain and an appropriate Lyapunov-Krasovskii functionals, it is shown that the closed-loop system is globally asymptotically stable. Finally, a numerical example is provided to illustrate the effectiveness of the proposed design scheme. |
