摘要
一、前言 由邓聚龙提出的灰色系统理论[1—4]业已在经济、农业、工程技术、医学、生物及系统工程等许多领域获得了广泛的应用并收到了显著的效果。 灰色系统理论的主要研究对象是本征灰系统。
Grey model can be applied to describe dynamic characteristics of complex systems.However, it is difficult to get some useful physical interpretation by this model,because its description is indirect. According to the method to build the grey model,a method called relative sustitution is proposed in this paper.Consequently a model called direct grey model,by which the dynamic system characteristics can be directly described, is derived.On this basis, two properties of a kind of direct grey model under a linear transformation are derived. One of them may be applied to the estimation of step inteference signals in adaptive control.
