含不确定参数的时滞非线性系统的鲁棒镇定性

Robust Stabilization for a Class of Nonlinear Time delay Systems with Uncertainty

讨论了一类含不确定参数的时滞非线性系统的鲁棒可镇定性．利用代数Ｒｉｃｃａｔｉ方程的正定解以及Ｌｙａｐｕｎｏｖ稳定性的概念，得到了该系统可由状态反馈控制器镇定的充分条件，并给出了控制器的设计．

Focused on the problem of robust stablization for a class of nonlinear time delay systems with uncertainty,this paper presents state feedback controller which stablizes the systems for all admissible uncertainties and non negative delays.The robust controller can be synthesized by using simple formulae.Illustrative example is given to demonstrate the applicability of the proposed approach .
