| 摘 要： | 本文给出了复杂系统模型结构辨识问题的基本假设和定义;论述了结构辨识的基本问题;证明了模型结构辨识问题可以看作是根据有限观测数据并利用建模时采用的外部准则来选择模型结构和参数的问题.文中分析了无偏结构的必要条件和模型筛选用的几个基本的外部准则,讨论了观测数据分割问题.

| Abstract: | This paper deals with the structure identification problem of complex system models. Some basic propositions and definitions are given. The structure identification problem is proved to be just one of how to choose model structures and parameters on the basis of the external criteria adopted in modelling and the finite number of observed data. The necessary conditions for the unbiased structure are discussed. Some basic external criteria for the selection of model structures are proposed. The partition of observed data are also dealt with. |
