研究了一类具有时滞驱动和有界扰动的不确定非线性系统的饱和控制问题。控制上的界是先验已知的，并且可以通过改变反馈增益来调整。一个基于Lyapunov的稳定性分析，利用Lyapunov-Krasovskii（LK）泛函证明一致最终有界跟踪，尽管在动态的不确定性。最后给出了一个数值例子来验证该控制器的性能。(C)2013爱思唯尔有限公司保留所有权利。
This paper examines saturated control of a general class of uncertain nonlinear systems with time-delayed actuation and additive bounded disturbances. The bound on the control is known a priori and can be adjusted by changing the feedback gains. A Lyapunov-based stability analysis utilizing Lyapunov-Krasovskii (LK) functionals is provided to prove uniformly ultimately bounded tracking despite uncertainties in the dynamics. A numerical example is presented to demonstrate the performance of the controller. (C) 2013 Elsevier Ltd. All rights reserved.
