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.

一类不确定前馈时滞非线性系统的自适应输出反馈调节

本文针对一类不确定的前馈时滞非线性系统解决了全局输出反馈调节问题。与以前的工作不同，正在考虑的系统类别中的非线性函数由输入输出函数乘以未知参数和线性未测状态所决定。通过仅使用一个动态增益和适当的Lyapunov-Krasovskii泛函，可以证明闭环系统是全局渐近稳定的。最后，提供了一个数值示例来说明所提出的设计方案的有效性。
