求解线性时不变系统传递函数矩阵的一种简单方法

A Simple Method of Evaluating the Transfer Function Matrix of Time Invariant Linear System

给出了基于半面逆矩阵计算线性时不变系统传递函数矩阵的一种方法，与传统的方法不同，这种方法不需要计算矩阵（ｓＩ－Ａ）的逆，而是用较简单的方法计算传递函数矩阵。并论述了在这种方法中如何使用分块矩阵运算来减小所涉及的矩阵的维数，最后给出了使用这种方法的例子。

In this paper,a method is presented for the calculation of the transfer function matrix depending on one-side inverse matrix of time invariant linear systems. Unlike conventional methods,this procedure dose not requre the inversion of the matrix (sI-A). Instead,it leads to a simpler calculation of the transfer function matrix. We also show how to use block matrix operation to reduce the dimensions of the matrices involved in the method. Finally,an example is given to illustrate the method.
