摘　　要：针对一类带时滞状态扰动的系统,讨论了系统的鲁棒自适应镇定问题.当扰动有界且界未知时,运用自适应控制方法,设计出一类自适应控制器.采用Lyapunov＿Karasovskii函数方法,证明了文中所提出的控制器可鲁棒镇定该系统.For a class of systems with delayed state perturbations,the problem of adaptively robust stabilization was discussed. The bound of the perturbations was assumed to be unknown.By using the adaptive control method,an adaptive controller was designed. Based on the Lyapunov-Karasovskii functional,it was shown that the dynamical system can be robustly stabilized by the adaptive controller.
