Automated System-Adviser Based on a Model for Control of the Technological Process of Concentrate Production

摘要

At processing units of beneficiation plants, management and control over ore concentrate production process is performed by an operator working from the automated work station. The operator sets the parameters of the equipment operation intuitively, based on the experience and the provisions of the manufacturing specification for ore concentrate production. The complexity of setting the equipment parameters is conditioned by the necessity to take into account simultaneously a great number of factor (such as: base ore quality, equipment integrity, basic ore availability and others). The paper suggests increasing the efficiency of managerial decisions by means of implementing intellectual add-in to the existing automated control system. The add-in is realized in the form of assistant system, based on the optimization mathematical model of control over ore concentrate production process. The suggested approach based on the information about the technological process enables conducting assessment of the controlled factors effects on iron-ore concentrate qualitative characteristics and energy consumption. It allows the user of the system-adviser to choose options for adjustment of the controlled parameters of a technological process to optimize it according to one or several criteria. Practical implementation of the suggested approach within the framework of the existing automated control system will allow the operator to receive recommendations about the correction of a control parameter of the technological equipment operation regimes in the real time and on the basis of the current (factual) values of the section parameters in crushing-and-preparation plants on the basis of the chosen by the user technical or techno-economic optimization criteria.
