| 摘 要： | 在线性系统可观测的情况下,研究了降维状态观测器设计问题。通过非奇异线性变换,得到代数等价系统的同时分离出需观测的部分状态。基于Sylvester矩阵方程的参数化解,给出降维观测器的增益矩阵的参数化表达形式,从而给出了线性系统的降维状态观测器设计的一种参数化方法。数值算例表明：所提降维状态观测器的参数化设计方法是简单有效的。

| Abstract: | On the case of observability of linear systems,the design problem of reduced-order state observers is studied.By using some non-singular linear transformation to the linear system,the corresponding algebraic equivalent system is obtained and a part of states needed to be observered are isolated.Based on the parametric solutions of a Sylvester matrix equation,a parametric expression for the gain matrix of reduced-order state observers are presented,and a parametric design method of reduced-order state observ... |
