| 摘 要： | 考虑含有未知输入的变时滞非线性系统观测器设计问题,本文分两部分论述,首先提出针对线性时滞系统的不含内时滞项的观测器系统化设计方法,给出观测器存在的充分条件,其次对时滞非线性系统利用代数R icat-ti方程解的条件设计出一种鲁棒观测器,并给出渐近稳定观测器存在条件。

| Abstract: | This paper presents the observer design for a class of delay-time nonlinear systems with unknown inputs.The objectives are twofold.Firstly,a simple and systematic design method of observers without internal delays for the linear time-delay system is studied,sufficient conditions for the existence of these observers are given.Then a robust observer using the solution of an Algebraic Ricatti Epuation for the class of nonlinear systems is proposed.The existence conditions of these asymptotically stable observers is given and proved. |
