Development Of An Imitation Model Of The Vulcanization Process In The Production Of Elastomeric Composites, Toshtemir Avezov, Mirxalil Agzamovich Ismailov
Development Of An Imitation Model Of The Vulcanization Process In The Production Of Elastomeric Composites, Toshtemir Avezov, Mirxalil Agzamovich Ismailov
Chemical Technology, Control and Management
In the article, a systematic approach to the mathematical modeling of the production process of complex multi-stage elastomeric composites was considered, which allows to take into account the stoichiometric relationship of the chemical reaction in the process. Based on the chemical reaction occurring in the mixer, a kinetic model of the elastomer composites production process is proposed, which is the basis for obtaining the main functional relationship of the mathematical model for the mixer, the main quality indicator of the process. The proposed systematic approach in the form of a mathematical model based on the stoichiometric relationship and the …

Mathematical Description Of A Bleach Impregnation Reservoir, Bekobod Ibragimov
Chemical Technology, Control and Management
This article discusses the issues of constructing a mathematical model of the technological process of bleaching textile materials in an impregnating reservoir using the heat balance equation, on the basis of which a qualitative analysis of the dynamic properties of an object has been carried out in order to create highly efficient control systems with the use of energy-saving technologies. While constructing a mathematical model characterizing the established and non-established modes of the control object (impregnating reservoir) used changes in heat flow and mass velocity of the incoming tissue. An algorithm for constructing a mathematical model of the process of …

Mathematical Models Of New Magnetoelastic Sensor For Measure Of Power And Vibration Parameters, Javhar Sulton Ugli Fayzullayev
Mathematical Models Of New Magnetoelastic Sensor For Measure Of Power And Vibration Parameters, Javhar Sulton Ugli Fayzullayev
Chemical Technology, Control and Management
In the paper, the mathematical models of the new magnetoelastic sensor for measuring power and vibration parameters are developed taking into account the aggregation or scattering of the parameters of electromagnetic chains and the characteristics of the magnetization curve of the magnetic conductor material. The analysis of the generated mathematical models and graphs based on them showed that the magnetic chain in which the coils are assembled does not take into account the nonlinearity of the magnetization curve of the magnetic conductive material (electrotechnical steel), the result is 12 ÷ 15% of the experimental results. It varies by 6 ÷ …
Structural – Parametric Analysis And Synthesis Of Glass Furnace Condition Observer, Utkir Uktam O‘G‘Li Kholmanov
Structural – Parametric Analysis And Synthesis Of Glass Furnace Condition Observer, Utkir Uktam O‘G‘Li Kholmanov
Chemical Technology, Control and Management
A modified Kalman filter of the glass cooking process is synthesized, taking into account perturbations in the form of a sequence of colored noises. The possibility of expanding this filter by noise filters to improve functioning in the presence of low-frequency disturbances is studied and a corresponding estimation scheme with additional noise filters is proposed. The results of the simulation allow us to assume that low-frequency disturbances in the glass furnace act at the input and affect the state of the control object.

Mathematical Modeling Of Thermal Processes Of Traction Asynchronous Engines For Diagnosis And Control Of Their Technical Condition, Nilufar Rabbanaqulovna Avezova, Javharbek Sulton Ugli Fayzullayev
Chemical Technology, Control and Management
Mathematical models of thermal processes of traction asynchronous motors are developed. A traction asynchronous motor is considered as a thermal system consisting of three bodies (stator winding, stator magnetic core and rotor), which take into account the heat exchange not only between the corresponding bodies, but also the heat exchange between each body and the environment. It is shown that the steady excess of the stator winding temperature of a traction asynchronous motor depends on the multiplicity of the stator winding current, the coefficient of electrical energy loss, and also on the temperature coefficient of the resistance of the winding …
