摘要

提出了一种设计模态观测器的方法，该方法既能实现小的特征值灵敏度，又能衰减由初始条件不匹配引起的估计误差。该设计方法基于最小化代价函数，该函数依赖于观测器模态矩阵的范数、条件数和初始条件不匹配的方向信息。并与之前的设计方法进行了比较，说明了该设计方法的优越性

Robust modalized observer with flight control application

The authors propose a method for designing modalized observers which achieves both small eigenvalue sensitivity and attenuation of the estimation error caused by an initial condition mismatch. The design approach is based on minimizing a cost function which depends on the norm of the observer modal matrix, its condition number, and directional information about the initial condition mismatch. The design method is compared with a previous approach to show its advantages.<>
