非线性关联大系统的鲁棒观测器研究

On Robust Observer for Nonlinear Large Scale Interconnected Systems

本文研究一类含有参数不确定性的非线性关联大系统的鲁棒状态观测器设计问题，设计了一种非线性鲁棒状态观测器，并证明了状态误差按指数渐近收敛到零。最后给出了一个数值算例，说明了本文的结论及鲁棒状态观测器的设计方法。

The design problem of robust state observer for a class of nonlinear large scale interconnected systems with uncertainties is considered in this paper. A nonlinear asymptotic state observer is constructed, and it is shown that the state error exponentially tends to zero. Finally, a numerical example is given to illustrate the result of this paper and method of design of observer.
