线性系统的一种改进的降阶方法

An Improved Method of Model Reduction in Linear Systems

本文从脉冲响应能量的观点讨论了平衡状态方程的降阶问题.文中提出了一个新的降阶准则,从而改进了Moore 方法存在的不足.两个数值例子,说明了该准则的优越性.

This paper discusses the order reduction of a space model in a balanced state inthe view of impulse response energy.Then,a new criterion of model reduction is pres-ented to improve the Moore's method,and two numerical examples are given to showthe validity of the criterion.
