本文研究了一类不确定非线性时滞系统的全局实际输出跟踪问题。在系统非线性涉及时滞的温和条件下，构造了一个具有可调缩放增益的齐次状态反馈控制器。通过齐次Lyapunov-Krasovskii泛函数，调整尺度增益以控制由齐次生长条件有界的时滞非线性，使闭环系统的所有状态保持有界时跟踪误差可以任意小。
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.
