The problem of output feedback adaptive stabilization for a class of uncertain dynamic system including time varying delayed perturbations was discussed.The uncertainties were assumed to satisfy the so-called matching conditions and the transfer function matrix of the nominal system was strictly feedback positive real.By using of the Lyapunov stability theory and Lyapunov-Krosovskii functional we proposed an output feedback adaptive controller,which guarantees that the closed-loop system is globally stable i the sense of uniform ultimate boundedness. Finally, an illustrative example was given to demonstrate the validity of the results.
