摘要
给出系统Ⅱ型聚集条件，在系统与其Ⅱ型聚集的可控性和可观性Ｇｒａｍｉａｎｓ矩阵之积范数之差最小意义下，把系统的Ⅱ型聚集作为其降阶模型。用此方法讨论－１８阶系统的模型降阶问题。
Aggregation Ⅱ is presented in this paper. Choosing Aggregation Ⅱ of the system as its reduced order model is based on minimization of the difference between the controllability and observability Gramians of the system and its aggregation in the norm square sense. The model reduction of a 18th order system has been considered by Aggregation Ⅱ.
