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。
In this paper, we study the design of a class of robust observer for nonlinear systems with parametric uncertainties. A new design scheme of nonlinear robust asymptotic state observer is proposed. The exponential asymptotic convergence of state observables error is proved. Finally, the result is applied to a drive system. The simulation results show that the design proposed in this paper is effective.
