Abstract

This work is devoted to management of material structures based on fractal presentations. Fractal material structures are formed due to positive feedback. The first stage is described: formulation of the identification problem of material structures based on fractal presentations. Fractal nature of materials is mentioned in numerous recent studies, herewith, generation of fractal structures is attributed to mechanisms of positive feedbacks. Fundamental physicochemical regularities of origination and transformation of material structures are currently developed and presented in such form that it is difficult to apply them for synthesis of control algorithms of structures. In other words, they do not meet the requirements to control models: output impacts are not disclosed as a function of external factors. It would be reasonable to develop fractal models of structures (that is, to identify material structures) with subsequent development of control impacts, in particular on parameters of positive feedback, in order to predict and modify material structure as required. This corresponds to the synthesis of control algorithms with estimation of controlled object and selection of coefficients of controller gain. The identification problems of images of actual material structures are formulated on the basis of presentations of dynamic chaos. These formulations of the problems have been used for development of methods and algorithms of identification of material structures in various industries, including mining and metallurgy.

基于分形表示的材料结构识别问题

摘要

这项工作致力于基于分形表示的材料结构管理。由于正反馈而形成分形材料结构。描述了第一阶段:基于分形表示的材料结构识别问题的制定。在最近的许多研究中都提到了材料的分形性质,因此,分形结构的产生归因于正反馈机制。材料结构起源和转变的基本物理化学规律目前正在以这样的形式发展和呈现,以至于难以将它们应用于结构控制算法的合成。换句话说,它们不符合控制模型的要求:输出影响不作为外部因素的函数进行披露。开发结构的分形模型(即识别材料结构)以及随后控制影响的发展,特别是对正反馈参数的影响,以便根据需要预测和修改材料结构,这将是合理的。这对应于控制算法与受控对象的估计和控制器增益系数的选择的综合。实际材料结构图像的识别问题是在动态混沌表示的基础上提出的。这些问题的表述已被用于开发各种行业(包括采矿和冶金)中材料结构的识别方法和算法。特别是在正反馈参数上,以便根据需要预测和修改材料结构。这对应于控制算法与受控对象的估计和控制器增益系数的选择的综合。实际材料结构图像的识别问题是在动态混沌表示的基础上提出的。这些问题的表述已被用于开发各种行业(包括采矿和冶金)中材料结构的识别方法和算法。特别是在正反馈参数上,以便根据需要预测和修改材料结构。这对应于控制算法与受控对象的估计和控制器增益系数的选择的综合。实际材料结构图像的识别问题是在动态混沌表示的基础上提出的。这些问题的表述已被用于开发各种行业(包括采矿和冶金)中材料结构的识别方法和算法。实际材料结构图像的识别问题是在动态混沌表示的基础上提出的。这些问题的表述已被用于开发各种行业(包括采矿和冶金)中材料结构的识别方法和算法。实际材料结构图像的识别问题是在动态混沌表示的基础上提出的。这些问题的表述已被用于开发各种行业(包括采矿和冶金)中材料结构的识别方法和算法。
