| 摘 要： | 分析了一类非线性延时系统的观测器设计问题。为了分析非线性函数对观测器设计的影响,提出了一类准单边Lipshitz条件。在准单边Lipschitz条件的基础上,得到了可渐近估计任意状态的延时无关和延时相关的观测器设计充分条件。这些充分条件可描述为线性矩阵不等式的形式。此外,即使非线性延时系统的参数对(A,C)是不可测的,这些充分条件依然是有效的,因为不必正定的准单边Lipschitz矩阵包含了很多非线性部分的有用信息。

| Abstract: | Observer design for a class of nonlinear time-delay systems is dealt with.A quasi-one-sided Lipschitz condition is introduced to estimate the influence of nonlinear vector function on the observer design.Delay-independently/delay-dependently sufficient conditions for observer to asymptotically estimate any state vector are presented which can be formulated in the form of linear matrix inequalities.Furthermore,these sufficient conditions for observer design are available even if the pair of nonlinear delay system is undetectable,because the not necessary positive quasi-one-sided Lipschitz constant matrix includes much useful information of the nonlinear part. |
