摘要
本课题的研究内容是对大系统进行有向图建模,并掌握一种适用于动态大系统的图论表达方法.大系统理论对研究和处理复杂的社会系统、经济系统、生态系统等, 有着很独特的作用和价值.
首先为本课题的研究做一些准备知识,学习并掌握图论、大系统理论及状态空间模型的相关知识.
其次,文章的第二部分以状态空间描述为基础,用动态方程描述所研究的动态反馈系统,然后确定状态空间模型及其有向图的映射.第三部分主要讲的是大系统的结构矩阵和状态重排.对于给定的结构矩阵,根据既定的规则可构建出其有向图.又由于大系统中的系统矩阵具有高度的稀疏性,对其点的排列不会影响有向图,则可对其状态矩阵进行适当的排列.论文的第四部分主要是根据结构矩阵对的性质判定所研究的结构矩阵对是否是结构能控的,或是结构能观测的.若一类系统既是结构能控的又是结构能观测的,则该系统是结构完备的.再者对结构特性的广义性进行讨论.每部分的最后都介绍了相关知识是国内外研究发展情况.
最后,总结了本文的主要内容.

Abstract
The research project is to conduct a model of directed graph to large -scale system and to master the expression of graph theory approach for a dynamic large-scale system.Large scale system theory has a unique role and value of researching and dealinging with complex social system, economic system and ecological systems.
At first we should do some preparatory knowledge for the research project,learning and mastery the knowledge of graph theory, large-scale systems theory and the state space model.
Secondly,the second part of the article is based on the state space description and uses dynamic equation to describe dynamic feedback system,then determine the mapping of state space model and directed graph.The third part is primarily concerned with the structure of large system matrices and state rearrangement .We can construct the directed graph of structure matrix on the established rule.Furthermore the high degree of scarcity of system matrix in large-scale systems,makes it true that the rearrangement of points does no affection on its directed graph,and then we can make a proper order of state matrix.The fourth part is mainly according to the nature of the structure matrix,we can determine whether the structure of matrix structure can be controlled, or can be observed.A system will be well-structured if its structure not only can be controlled but also can be observed.Then we make a discuss about the generalized nature of structural properties.The end of each section is presented of research development at our country and abroad.
Finally, I sum up the main content of this article.
