Implementation of fuzzy logic in the smelting process of control algorithms of copper-nickel sulfide materials

Abstract

The analysis of control quality of technological process of melting of copper-Nickel sulfide materials is carried out. The structure of the automatic melting control system is proposed, information and control channels are described. The algorithm of process control using fuzzy logic, which allows stabilizing the copper content in the matte within the specified limits.

Determination of regression coefficient for numerical models of adsorption isotherms

“…From this, it can be seen that the Langmuir -Freundlich 2 adsorption isotherm, shown in figure 2, coincides most accurately with the experimental graph. The mass of the adsorbent 𝑚 𝑐 , necessary for the absorption of alcohol concentration С 0 = 10 • 10 −3 kg/m 3 for 4 hours, is calculated by [11]:…”

“…The following initial values: water consumption 𝑊 = 0,00012m 3 /s, input concentration of ethyl alcohol С 0 = 10 • 10 −3 , kg/m 3 , air temperature 𝑇 = 293 K, experiment time 𝜏 = 4 hours. The parameters calculations, required for the mathematical experiment, are presented below.The mass of the adsorbent 𝑚 𝑐 , necessary for the absorption of alcohol concentration С 0 = 10 • 10 −3 kg/m 3 for 4 hours, is calculated by[11]:…”

Discrete Element Simulation of Powder Sintering for Spherical Particles

“…Currently, studies are underway [5][6][7][8], a methodology has been developed to determine the DEM parameters of bulk materials based on machine vision and a neural network algorithm [9][10]. This technique allows you to obtain the exact values of the DEM parameters of the investigated bulk material by comparing the visual images of the material's behavior on the experimental stand in reality and in the model.…”
