一类不确定非线性系统的鲁棒状态观测器设计

Robust State Observer Design for a Class of Uncertain Nonlinear Systems

本文研究了一类具有参数不确定性的非线性系统鲁棒状态观测器的设计问题。提出了一种新的非线性鲁棒渐近状态观测器设计方案，证明了状态观测误差的指数渐近收敛性。最后将所得结果应用于一轴盘传动系统，仿真结果表明本文提出的设计方案是有效的。

The design problem of robust state observer for a class of uncertain nonlinear sys tems is studied in this paper. A nonlinear asymptotic state observer is constructed,and it is shown that the state-error exponentially converges to zero.Finally,it is applied to a disk-shaf tsystem and the simulation shows that the design method is effective.
