Automatic control system of pyrogas parameters in pyrolysis process in acetylene production

Nowadays, in the automation of technological processes, many digital devices are used in all areas of the industry, especially in the mining sector. With the high accuracy of digital devices, they are still affected by noise and interference, which can lead to a measurement device error. Therefore, many filters are used in the industry. The purpose of using filters is to reduce the amount of interference that affects. The article outlines an algorithm for forming noise affecting precision indicators of automation of technological processes using adaptive filters, which allows measuring instruments to reduce errors. Such a type of noise reproduces a useful signal specter and limits the possibilities of its debugging.

In this article, a simulation model of an intelligent control system for a bioreactor used in the bacterial oxidation process of sulfide deposits with complex, gold-enriched content is developed using the functional blocks from the Fuzzy Logic Toolbox library in the MATLAB software package. Furthermore, the mathematical model of the bioreactor is represented through its transfer function in the significant adjustment channel. A rule base is established to regulate the variation of input and output parameters for the fuzzy control system. The study reveals that employing a fuzzy controller for bioreactor systems is an effective method for system adjustment.

The problem of describing the contact curves of technological machines has been solved. At the same time, contact interaction was studied taking into account changes in the technological parameter and deformation of the materials of the contacting bodies. The obtained dependencies make it possible to find rational parameters of the technological process with sufficient accuracy. The obtained models indicate that the shape of the contact is influenced by such parameters as strip thickness, roll radii, external forces, as well as parameters characterizing the deformations of the contacting bodies.
