一类非线性系统降维观测器的设计

A Design Way of the Reduced Observers of Nonlinear Systems

与线性系统一样，非线性系统状态观测器，按其结构可分为全维观测器和降维观测器。基于对Riccati方程的求解，本文对具有主线性部分，非线性部分满足Lipschitz条件的非线性系统给出了一降维观测器的设计方法，并讨论了该方法的适用性。

Like the linear systems,the observers of nonlinear systems,based on their structures,possess two forms:the full observers and the reduced observers.Based on the solution of the Ricati Equation,a design way of the reduced observer is developed for a special type of nonlinear system which have the main linear part and the nonliear disturb part satisfying the Lipschitz condition.At the end,the applicability of the design way is discussed.
