有零极点的系统的一种截尾降阶法

Balanced-truncation Model Reduction for Systems with Poles at the Origin

将Ｓｃｈｕｒ平衡截尾降阶方法推广至原点处有极点的多变量系统，得到数值稳定的降阶算法，并以数值例子说明该算法的具体应用。

In this paper, Schur balanced-truncation model reduction algorithm is generalized to multi-variable systems with poles at the origin, the numeral stable reduction algorithm is obtained, and numerical examples are given to demonstrate the applications of the algorithm.
