Adaptive robust stabilization of a class of nonlinear systems with matched time-delay state disturbances
一类具有匹配时滞状态扰动的非线性系统自适应鲁棒镇定

The paper discusses adaptive robust stabilization for a class of nonlinear systems with matched time-delay state disturbances.The upper bounds of the time-delay state disturbances depend on time-varying functions and contain unknown parameters.Adaptive laws are proposed to estimate the unknown parameters,and robust controllers are designed using the estimated values.Based on Lyapunov-Krasovskii function,it is shown that the closed-loop system is stable in the sense of uniform ultimately boundedness.Finally,a numerical example is given to verify the correctness of the conclusion.
