大系统能控型与能观型集结的直接迭代法

Direct Iteration Method of Observable-like and the Controllable-like Aggregation for Large Scale Systems

集结的思想和方法在大系统降维中具有十分重要的作用．本文基于通常采用的精确集结条件─—观测型集结，推导出理想集结条件的另一种形式─—控制型集结，同时给出在控制型集结条件下进行系统降维的直接迭代方法（简称ＤＩ法），并讨论了控制型集结模型及其用ＤＩ法所得简化模型的有关性质．

The concept and method of aggregation have very important use in model reducation of large scale systems.This paper gives another aggregation condition based on the usual one,which are called observable-like and controllable-like aggregation conditions.The direct iterate method of controllable-like aggregation is given and the characters of the corresponding reduced model are discussed.
