Appling nonlinear feedback with estimated parameters and state diffeomorphism, Based on the Lyapunov approach we can develop a kind of novel robust controller designed for a class of nonlinear systems with mismatched uncertainty.

针对反馈可线性化系统，利用含估计参数的非线性反馈及状态微分同胚，基于李亚普诺夫方法给出了含非匹配不确定性系统的新型鲁棒控制器的设计方案。

The author give ways to construct Liapunov function of a lagrange system with energy consumption: One gives qualitative analysis of the mechanical system, the other gives quantitative estimation as well as qualitative analysis of the asymptotic stability of the studied mechanical system.

论文工作如下：(1)提出了非保守力学系统的李亚普诺夫函数构造途径：定性分析的能量函数方法和可用于定量分析的系统分解方法，并给出了分别使用上述方法的充分性条件。
