The article presents a mathematical model of an automated process control system for the production of lubricating coolant. The transfer function of the control object, the heater, is obtained. The optimal coefficients of the control device — the PID controller — are calculated. The transition process of the system is built. Management quality indicators have been determined.
The article describes the technological process course and the main task of the water preparation process for cooling the power generator of a thyristor frequency converter. The parameters affecting the quality and safety of the technological process are revealed. In order to import substitution of automation tools in this technological process, a modern automated control system based on Russian-made microprocessor technology is proposed for implementation.
In this paper, spiral antennas are investigated, during the analysis of the synthesis of two-way spiral antennas using a fundamentally new approach, it will be possible to apply for a rapid change of polarization without antenna reconstruction and use in mass circulation.
This article discusses the issues of constructing mathematical and computer models of complex radio engineering systems, which allow us to assess the quality of their functioning at the design stage, before carrying out full-scale tests. The features of modern radio engineering systems that complicate the tasks of their research and design using mathematical modeling are also highlighted. These features include: the software and hardware complexity of the RTS, the stochastic nature of the processes occurring in the RTS, the high rate of change of radio signals with a relatively low speed of information flow. The above methods make it possible to facilitate the process of constructing mathematical models of complex systems, radar signals and interference. The general sequence of actions for creating a mathematical model of a radio engineering system and conducting research on it using a PC is shown.
The article considers a normative approach to the creation of an functional model of a wind farm controller based on special control logic nodes for monitoring active and reactive power. The attributes of the data classes of logical nodes representing general and wind energy information about the control systems of the active and reactive power of the wind power plant are given in tabular form. A graphic illustration of the functions performed by the wind farm controller provided by the control logic nodes is presented.
Development of agricultural activity means existence of a large number of a livestock and crop substratum which is reasonable for throwing out on fields as fertilizers not at once, and to use as raw materials for the purpose of receiving biogas. Waste, getting to preliminary account capacity, mix up with a press and water, are led up to the necessary consistence and temperature. The most effective gas discharge is observed when loading and discharge of weight are continuous. A certain frequency of hashing and temperature condition is characteristic of each phase of a sbrazhivaniye. Thereby there is a need of creation of the multichamber reactor of continuous loading of raw materials in which regulation by temperature condition and hashing for each chamber separately is carried out. In this article authors offer to consideration such reactor with automatic independent hashing in different chambers, proceeding from sbrazhivaniye phases, and also automated management of heating of chambers for reduction of energy consumption and maximum efficiency of processing
