一种改进的Lipschitz非线性系统观测器的设计

Improved observer design for Lipschitz nonlinear systems

运用微分方程方法 ,讨论了一类满足 L ipschitz条件的非线性系统观测器的设计 .结论表明 :只要系统可观 ,稳定观测器总是存在的 ,改进了以往认为稳定观测器设计不仅与系统矩阵的特征值有关 。

This paper presents a new design method of observers for the class of Lipschitz nonlinear systems. Our results show that the observer design for such systems can be converted into linear observer design. The view that observer existence is not determined purely by the eigenvalues of the system matrix has been modified. Finally an example is given to illustrate our results.
