Abstract
Context. Resolves an an actual task of developing advanced mathematical models to study regulation of the roasting trucks speed of the conveyor machine that allows to maintain a predetermined level of height pellet layer and provides optimal process for firing pellets and maximum performance Objective is a presentation of the mathematical model development results for the regulation roasting trucks speed of the conveyor machine with implementation modern SCADA-system for controlling the conveyor machine performance by regulating its moving speed roasting trucks, which leads to a change of height of the pellet layer on the trucks. Method. To evaluate the dynamic characteristics of the drive system and the simulation control the speed of movement of the roastingtrucks conveyor machine uses a powerful and universal method of research – graphical environment Simulink simulation modeling, which is a supplement to the package MATLAB for numerical analysis. When using Simulink simulation uses the principle of visual programming, in accordance with which the user on the screen of the library of standard blocks and creates a device model performs calculations. Results. The proposed mathematical model used baseline data of conveyor machines OK-306 and LURGI-278. To construct a mathematical model of the automated speed control system for moving the roasting trucks conveyor machines have calculated transfer functions of elements included in the system. As a result of simulation obtained transients when adjusting the height of the pellet layer on the roasting carts and determine their impact on the performance of the conveyor machine. For the feasibility of improving the control system pelletizing plant by the use of a mathematical model for the regulation of the speed of roasting trucks designed modern model interface SCADA-system that works in real time, and enables operational dispatch management. As the SCADA TRACE MODE 6, the height of the pellet layer control system should be developed using SCADA TRACE MODE 6 pelletizing plant systems leading automated management tool using the system. Conclusions. On the basis of the use of the output of the technological process of roasting of the pellets on the conveyor of the burning car and the calculations in a graphical environment Simulink MATLAB built a mathematical model of the system for controlling the speed of the roasting trucks conveyor machine in accordance with technological process allows to investigate influence on pellet burning process by controlling the height of the pellet layer and the performance of the conveyor machine. The proposed model of a modern SCADA-system interface that works in real time and enables operational dispatch management, can be used in real industrial environments.
