Nazarenko M. The development of theory of integrated control by technological complexes of iron ore mining and processing enterprises

The dissertation is devoted to the decision of actual scientific problem of development of the theory of control by technological complexes and of construction of the optimum integrated control system by technological processes of processing and enrichment of iron ore at ore mining and processing enterprise. Thus, it is using the identification of technological parameters of iron ore processing and enrichment processes for construction of mathematical model which factors are updated on each step of calculation, and the initial data for calculation of model's factors get out as set which vectors are most close located to a vector of the current situation and are characterized by the most probable factors of correlation between the input and output data, and the further optimization of this model's factors determines the settings of regulators of the integrated control system for maintenance of rational operating modes of iron ore enrichment process. In work it is proved, that for construction of dynamicdifferencing model of iron ore enrichment process on the basis of Wiener-Hopf's equation, and for calculation of quantization interval of technological process's parameters on the basis of using of its spectral characteristics, there is enough to use the limited quantity of values of correlation functions of technological process's parameters because they characterize the closest connections between input and output influences, and it does not result in decrease of accuracy of model's calculations, and reduces the calculation of correlation functions. In work it is forming the mathematical model for control of technological iron ore enrichment process as multiconnected digital system on the basis of using of return operator method, thus it is entering in a contour of control the additional feedback which result is optimization of regulator's factors that results in essential reduction of a control mistake. There was developed the techniques of parameters estimation for choice the way of control of systems with the casual revolting influences in conditions of ore mining and processing enterprise which have allowed on example of Inguletsky ore mining and processing enterprise to prove scientifically a principle of calculation of optimum parities of ore charge's mineral versions which gives from motion for processing and enrichment, the content of +20 mm class on output of crushing factory, the productivity of enrichment section, the content of -44 micrometer class in a concentrate and of other parameters, and thus to detect parameters of the quality, the quantity, the cost price of iron ore concentrate, and also settlement profit by its production. The results of researches are introduced on a number of ore mining and processing enterprises, scientific and project institutes, enterprises as numerous techniques, technical projects and performance of research works, and also at composition of educational working plans for students of Kryvyi Rih technical university.
