In this paper, we study the problem of global practical output tracking via state
feedback for a class of uncertain nonlinear time-delay systems. First, unnder mild conditions on the
system nonlinearities involving time delay, we construct a homogeneous state feedback controller
with an adjustable scaling gain. Then, by a homogeneous Lyapunov-Krasovskii functional, the scaling gain is adjustedto dominate the time-delay nonlinearities bounded by homogeneous growth
conditions and render the tracking error can be made arbitrarily small while all the states of the
closed-loop system remain to be bounded
