一类非线性扰动时滞系统的基于观测器的鲁棒控制

Robust Stabilization of a Class of Uncertain Time delay Systems with Nonlinear Perturbation

讨论了一类不确定时滞系统的基于观测器的控制器设计问题,其中不确定是非线性时变的.在非线性不确定性满足有界条件下,通过构造增广系统,利用Lyapunov稳定性理论,给出了该不确定性系统基于观测器的鲁棒镇定的充分条件,并给出了相应的状态观测器和鲁棒控制器.

Robust stabilization of a class of time-delay systems with nonlinear time-varying perturbation is discussed in this paper.On condition that the nonlinear uncertain function is bounded,based on state observer and controller,we derive a sufficient condition for robust stability independent of delay by the Lyapunov functional theory.
