Abstract:
In this paper, the problem of global practical output tracking is
investigated by state feedback for a class of uncertain nonlinear time-delay
systems. Under mild conditions on the system nonlinearities involving time
delay, we construct a homogeneous state feedback controller with an
adjustable scaling gain. By a homogeneous Lyapunov-Krasovskii
functional, the scaling gain is adjusted to 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.
