The modern development of the food industry is accompanied by an ever wider application of automated control systems for technological processes. The prerequisites for this are: the growth of the enterprise's capacities; the use of continuous and continuous production methods; equipment of enterprises with new high-performance equipment; presence of modern technological means of automation. The wide application of automated control systems is caused by a significant economic effect, which is achieved due to: the provision of specified qualities of produced products, regardless of subjective factors; reduction of losses of valuable products; reduction of labor intensity of production processes; increase of production culture. The main task of the automated control system is the observance of the technological regulations determining the permissible ranges of technological process parameters (temperature, flow, product composition), equipment performance, and quality process indicators. In addition, the tasks of controlling installations and lines include their starting and stopping, emergency protection and interlocking. In order to carry out the tasks of automated control of installations and technological lines, it is necessary to gradually remove the human operator from the control loop and transfer the control functions to the technological means of automation. At the same time, the operator must monitor the operation of automation devices and make decisions in complex situations. Modern sugar production is a complex technological process. Therefore, ensuring the uninterrupted operation of the production line, maintaining its high productivity, obtaining a product of the highest quality is the most urgent task in this area.

Model-Free Adaptive (MFA) control is a technology that has made a major impact on the automatic control industry. MFA control users have successfully solved many industry-wide control problems in various applications and achieved significant economic benefits. Now, the challenge is extending the many advantages of MFA control technology to diverse and fragmented markets, which could benefit from its unique capabilities. Since single-loop MFA controllers can directly replace legacy PID controllers without the need for "system" redesign (plugand play), they are readily embeddable in various instruments, equipment, and smart control valves. This alleviates concerns relative to cost of change and also makes MFA an appealing tool for OEM applications on a large scale.

Full textAbstract:
Currently, about 90–95% of generic controllers use the PID algorithm to generate control actions, while 64% of the PID controllers are used in single-circuit automatic control systems. Most of industries (power industry among them) use hundreds of automatic control systems. The quality of their work is the basis of economic efficiency of technical processes, ensuring safety, reliability, durability and environmental friendliness of both technological equipment and automation equipment. There are different modifications of PID-controller structure implementation. In practice the ideal PID controller with a filter and the classic PID regulator (serial connection of the ideal PI controller and the real PD regulator as the direct action elements) are widely used. The problem of choosing a rational structure and a method of parametric optimization of PID controllers, which provide the best direct indicatives of the quality in the development of the main effects in single-circuit automatic control systems, becomes urgent. However, only for the classical PID controllers, which are widely used at present, there are more than three hundred methods for adjusting the three parameters of the optimal dynamic adjustment, as well as the ballast time constant. This results in arising a problem of substantiation of the best structure and method of parametric optimization of classical PID regulators. As a basic option, one of the simplest and most obvious one, viz. the method of automated adjustment of the controller in the Simulink MatLab environment had been chosen, which was compared with the method of full compensation in general for objects with a transfer function in the form of an inertial link with a conditional delay. Two variants of control action realization on the basis of the structural scheme of the optimal regulator developed by the Belarusian national technical University were also offered. In contrast with the classic PID controller, the optimal controller has one parameter of dynamic adjustment setting. The results of simulation of transients at basic perturbations confirmed that the best direct indicatives of the quality are provided with an optimal regulator, which makes it possible to recommend it for wide implementation instead of the classic PID controllers.

High productivity and power of technological and transport mechanisms, large capacity and number of storage equipment, a variety of types of grain crops simultaneously processed at the elevator require the operator to make a lightning-fast decision, the optimal choice of grain transportation routes.One of the first control systems consisted of huge energy-intensive cabinets with starting equipment, allowing remote control of equipment, without the functions of elementary control of their operation.As storage volumes increased, these systems were supplemented with relay cabinets, whose task was to conduct interlocked control of an ever-increasing number of mechanisms, so that at least somehow it was possible to control such a complex. These relay cabinets had a low degree of reliability (contact elements), consumed a large amount of energy, and required the constant presence of large maintenance personnel.The era of microelectronics has come, which completely changed the idea of the capabilities of control systems. At first, it seemed very expensive and not a quick payback. But every year, the cost of automation equipment is decreasing, reliability has grown to high levels and this technique has come to the management systems of grain storages and elevators.Modern automation at the majority of Ukrainian elevators makes it possible to control technological processes. At the same time, many processes are regulated in a mode that requires a sufficiently high qualification of service personnel. The exchange of data on the operation of SMART-INDIVIDUAL equipment is carried out by logical controllers by polling sensors, generating control actions, monitoring equipment operating modes with display in the WEB-interface system. The SMART-INDIVIDUAL system has undeniable advantages over existing centralized control and management systems. SMART technology is inextricably linked with the dispatch control and data collection system - SCADA, designed to monitor and supervise a large number of remote objects or one geographically distributed object. The SMART-INDIVIDUAL system is equipped with a module with a regulation for monitoring parameters, equipment according to the passport characteristics. At the same time, the system maintains an archive and controls the timing of maintenance. The laboratory installation SMART-INDIVIDUAL includes technological and transport equipment, which is most used in the elevator industry: air filter ZEO-FCS, bucket elevator ZEO-BE, scraper chain conveyor ZEO-DC. On the basis of the SMART-INDIVIDUAL software and hardware complex at the Department of Technological Equipment for Grain Production of the Odessa National Academy of Food Technologies, students are trained in the new specialty "IT service of equipment".

In the aerospace manufacturing industry, it is impossible to achieve precise and efficient automatic drilling and riveting for largescale composite board parts. The bottleneck is that the depth detection of rivet holes still relies on manual operation, which seriously affects the assembly efficiency and stability of composite board parts. In order to realize accurate and efficient on-machine automatic measurement for through holes in the automatic drilling and riveting process of largescale composite board parts, this paper presents a novel hole depth measuring device. Its mechanical structure is developed based on our newly designed measurement scheme and optical path, the purpose of which is to convert the hole depth data into displacement data of the probe motion. Its electrical hardware consists of three units: a laser transceiver unit to pick up laser spots; a displacement measuring unit to capture the probe movement in real time; and a driving unit to achieve motion control of the probe. Finally, the experimental results indicated that the proposed method and device are capable of performing automatic measurements for through-hole depth. In addition, factors affecting the measuring accuracy and stability of the device are initially analyzed and discussed, which lay a foundation for subsequent research on error compensation and probe calibration.

In recent years, especially in 2020, the demand for the products of greenhouse plants is increasing. Reducing the risks of the impact of the quality of energy supply, as well as reducing the cost of electricity due to the constant increase in tariffs are important tasks. Therefore, it is important to identify and analyze modern available technologies and equipment of Russian production for greenhouse farms. (Research purpose) The research purpose is in assessing the impact of the quality of energy supply on the technological processes of greenhouse farms, identifying and analyzing the existing modern domestic equipment that reduces the risks of the energy supply. (Materials and methods) Authors used a computational and analytical method for determining the average indicators of electric energy costs for technological processes in a greenhouse. The article presents a review of the automated greenhouse microclimate management system developed using the products of TM OWEN. (Results and discussion) Automated systems for controlling the greenhouse microclimate can reduce the impact of the quality of energy supply when deviating from normal values, minimize the impact of the human factor on the production process, and collect and archive the indicators of devices for further analysis. The system makes it possible to repair and replace failed equipment without stopping the production process and implies both fully automated and manual control, if necessary. The considered version of the automated greenhouse microclimate control system has been tested in practice and is used in the greenhouse economy of the Republic of Bashkortostan.

Currently, the means of measuring and converting information signals from equipment are widely used in industrial processing systems.
For the most part, modern systems of mechanical processing of materials use mainly single-channel systems that work on information signals that identify the physical parameters of the technological process. Such a narrow specialization of monitoring one of the parameters usually reduces the reliability of the results obtained and, as a consequence, the reliability of the entire control system.
The task of the work is to determine the possibilities of creating the foundations of the automated system on the basis of multi-channel information recording devices from processing equipment and possible approaches to the choice of criteria for the analysis of fluid information.
As a result of the given analysis of a condition of branch and its modern transformations, the module of system for data collection on process (from a set of sensors) is offered for development, with a possibility of their further transformation on certain dependence, storage, transfer, and a possibility of signaling of certain events, for example, faults, for use in production automation systems and for equipment not included in the systems.
At the same time, the multi-channel device of the sensor system provides opportunities to determine the full amount of information about the process. The basic modern means of control of work of technological processing CNC-equipment applied in the industry are investigated.
The most perspective directions of development of multicriteria methods and automated control systems of technological equipment in the part of creation of complex sensors are determined. These sensory complexes register signals that are different in physical phenomena. The main approaches to the creation of control systems provide opportunities to build a theoretical basis given the logic of the system of obtaining specific information data in the automation of technological processes.
Promising research at creating algorithms for such complex systems of quality control and diagnostics of technological processes can be aimed.

Purpose This paper aims to design an automatic inspection system for the characters on tire molds, which involves a vision-based inspection method for the characters on tire molds. Design/methodology/approach An automatic inspection equipment is designed according to the features of the tire mold. To implement the inspection task, the corresponding image processing methods are designed, including image preprocessing, image mosaic, image locating and character inspection. Image preprocessing mainly contains fitting the contours of the acquired tire mold images and those of the computer aided design (CAD) as the arcs of two circles and polar transformation of the acquired images and the CAD. Then, the authors propose a novel framework to locate the acquired images into the corresponding mosaicked tire mold image. Finally, a character inspection scheme is proposed by combining an support-vector-machine-based character recognition method and a string matching approach. At the stages of image locating and character inspection, image mosaic is simultaneously used to label the defects in the mosaicked tire mold image, which is based on histograms-of-gradients features. Findings The experimental results indicate that the designed automatic inspection system can inspect the characters on the tire mold with a high accuracy at a reasonable time consumption. Practical implications The designed automatic inspection system can detect the carving faults for the characters on the tire molds, which are the cases that the characters are wrongly added, deleted or modified on the tire mold. Originality/value To the best of the authors’ knowledge, this is the first automatic vision-based inspection system for the characters on tire molds. An inspection equipment is designed and many novel image processing methods are proposed to implement the inspection task. The designed system can be widely applied in the industry.

Purpose Electrospark deposition (ESD) attracts special attention from scientists and engineers because of its unique advantages. However, the ESD process has been carried out by hand up to the present. This prevents ESD from preparing complex curve/surface coatings owing to manual operation characteristics. To meet the coating precise preparation requirements for a lot of parts with complex surface from various industrial fields, this paper aims to obtain a new automatic ESD equipment, process and preparation methodology for complex surface coatings.

Full textAbstract:
The article deals with the issues of the spatial direction of measurement, which is optimal in terms of recognition of the state of a particular unit node and preparation of control points for diagnosis. To form a diagnostic feature, the representation of the signal in a rather narrow range has been used, for instance, in the area of one of the harmonics of the fundamental mechanism excitation frequency. To process such signals, an integrated programming environment developed in the style of Microsoft Visual products has been created. To ensure the requirements of optimal vibration analysis, the structure of stationary equipment control systems has been proposed. Analysis of random vibration of the diagnosed object is done using real-time two-channel analyzers. Each analyzer channel has a processor for fast Fourier transform and operational information. The two available channels can allow assessment of the state of the object by special correlation functions. In contrast to the known methods, the established methods of determining the frequency range of defects of various light industry machine nodes differ in taking account size of parts and equipment nodes, and the possibility to use narrow-band filtering. The analysis of possibilities to install vibration sensors has been carried out.

Full textAbstract:
A type-based system is widely used for cost and schedule control in the NATM (New Austrian Tunnelling Method) tunnel. This study raises several limitations of the type-based system: a broad level of control, a distributed approach to cost and schedule data, ad hoc management, and difficulty in deriving meaningful data. Integrated cost and schedule control promises a myriad of benefits on both information flow and construction management. Nevertheless, the integrated approach still seems to be a long way from common use in the construction industry because it requires considerable overhead effort to acquire, track, and analyze the integrated data. The objective of this study is to propose a new method to automate the required processes for implementing cost and schedule integration. We propose an operational-level automatic data processing system for cost and schedule integration. The proposed system consists of a real-time location system for detecting equipment locations, a wireless mesh network for transmitting the location signals to a field office, and a prototype model for transforming the signals to cost and schedule data. Technical feasibility is analyzed through a pilot project. The study offers a new approach to facilitating sensor technologies for cost and schedule integration.

This paper aims to improve the marble industry production chain by proposing new technological approaches using the Radio Frequency Identification (RFID) systems. The dynamic capabilities of the RFID read-write tags allow the storage of physical characteristics of stone blocks, according to electrical, ultrasound and three-dimensional image characterization tests. These characterization non-destructive tests allow the evaluation of important parameters of the original stone blocks, by analyzing the internal structure of the rocks. Then, these parameters can be stored in databases through RFID-tags, in order to optimize their subsequent cutting and transformation processes. RFID identification technology when integrated into an ethernet communication network enables automatic communication with cutting and processing equipment, building an intelligent industrial platform, integrating PCs (Personal Computers) and PLCs (Programmable Logic Controllers) within an Industry 4.0 environment. Another huge advantage of RFID technology is that it allows full product traceability, namely by enabling the end consumer to reverse the production path. A laboratory prototype was implemented and a detailed analysis and discussion of the obtained functionalities is shown at the end of this paper.

Pilling is an undesired defect of textile fabrics, consisting of a surface characterized by a number of roughly spherical masses made of entangled fibers. Mainly caused by the abrasion of fabric surface occurring during washing and wearing of fabrics, this defect needs to be accurately controlled and measured by companies working in the textile industry. Pilling measurement is traditionally performed using manual procedures involving visual control of fabric surface by human experts. Since the early nineties, great efforts in developing automatic and non-intrusive methods for pilling measurement have been made all around the world with the final aim of overcoming traditional, visual-based and subjective procedures. Machine Vision proved to be among the best options to perform such defect assessment since it provided increasingly performing measurement equipment and tools, serving the purpose of automatic control. In particular, a relevant number of interesting works have been proposed so far, sharing the idea of helping (or even replacing) traditional measurement methods using image processing-based ones. The present work provides a rational and chronological review of the most relevant methods for pilling measurement proposed so far. This work serves the purposes of 1) understanding whether today's automatic machine vision-based pilling measurement techniques are ready for supplanting traditional pilling measurement and 2) providing textile technology researchers with a bird's eye view of the main methods studied to confront with this problem.

Contactless converters of direct and alternating currents of control and control systems are widely used in them. Their disadvantages are a narrow range of controlled currents, large dimensions and weight. Therefore, it is important to eliminate them. The paper discusses the general principles of construction of contactless converters of large direct currents, the main requirements for them, and shows the results of the development of one of the options proposed by us, universal contactless magneto-modulation converters of large direct currents with an extended range for various control and control systems. They differ from the known ones by an extended controlled range with small dimensions and weight, and increased accuracy and sensitivity. The converter has a simple and technological design with low material consumption and cost, and can control large direct currents, as well as alternating currents, without contact. The paper considers the errors from external magnetic fields of universal contactless converters of control and control systems. It is shown that the error from the external magnetic field does not exceed 0.08% if the number of sections of the measuring winding is even and with their symmetrical arrangement, and with their even increase-the error decreases. At the same time, the developed contactless converters can be widely used in industry, metallurgy, railway transport, agriculture, water and farming, as well as in the electric power industry of “smart” cities and homes and for checking electric meters at the place of their installation.

In modern industry, various industries are widely used frequency converters (FС) to control the speed of rotation of asynchronous motors. Widely used frequency converters that feed asynchronous motors allow you to optimize production, reduce electrical energy consumption, increase the service life of equipment, etc. The article considers the system "frequency converter-asynchronous motor" as a complex nonlinear automatic control system. On the basis of the linearized transfer function of the frequency converter and the asynchronous motor, the block diagram of the open system "frequency converter - asynchronous motor"is made. The mathematical description of the system is written by algebraic controls in symbolic form. A program for generating the transfer function and calculating the roots of the characteristic equation using the MATLAB application package is presented. To determine the stability of the frequency converter - asynchronous motor system, a program is compiled where the stability of the system is determined by the characteristic roots of the equation. The transient curve of the speed and torque of an asynchronous motor confirms the adequacy of the block diagram "frequency converter-asynchronous motor" and its mathematical description.

For many water affairs and objectives the following functions are often of great importance:–automatic and continuous measurement of parameter and control and regulation of variables–digital acquisition of data, processing, and storage of data in-situ–quick and safe teletransmission of data to a computing or service centre. Thanks to computer-aided data acquisition and automated stations, today these functions can be performed in a cost-effective way. Furthermore, it is possible to profit by the efficiency and availability of such systems for a variety of projects in the field of water management. The paper describes a modern microprocessor-controlled and modular system of CMOS-technology, developed in the Federal Republic of Germany and widely used by authorities and in industry. An outstanding feature of the system is its great flexibility in the range of data acquisition and data teletransmission with the following possibilities:–data collection system (data logger)–data transmission via fixed linesvia telephone linesvia radio. Several examples show the application with hydrographs and water quality measurements, for the technical surveillance of waters and installations, as well as for the control and management of dams in view of drinking-water supply or agricultural irrigation, respectively. By means of these facilities on the basis of the measuring results, and after examination and evaluation of the information, topical decisions can be made which are founded on relevant strategies or model calculations. The use of the robust equipment is not only recommended for water authorities in industrialized countries, but also in developing countries for integrated measurement and information systems.

It was demonstrated that, despite the widespread implementation of modern software and hardware systems during the construction of new APCS and upgrading the existing ones for thermal power plants (TPP), improvement of the process control quality, optimization of their modes and parameters take place generally at the equipment and power unit level and to a far lesser extent – at the power plant level and as a result – insufficient level of automation and low technical and economic efficiency. Another conclusion from the performed analysis – when implementing control algorithms in the APCS based on the up-to-date SHS, their wide data and software capabilities are not fully used. The main ways of further APCS improvement for the purpose of further increasing of their efficiency and the level of intelligence of SHS based APCS of power plants are presented. The possibility of their implementation is considered with application of the basic principles laid in the concept Industry 4.0. The possible economic effect from the implementation of the proposed solutions for increasing the intelligence and efficiency of the SHS based APCS was assessed.

The fourth digital revolution of industry makes substantive changes to the rate and methodology of work performance. Machines and robots do the majority of work in robotized and automated factories, while people only supervise them. After an increase of production efficiency, quality control became a critical point. Therefore, quality control systems of computer visions are increasingly installed. The branch of chemical industry requires measurements of quality at as great a frequency as possible. Consequently, indirect measurements are effectively used at this point. This research presents the method of indirect particle measurement. Particles are measured using digital image processing. The algorithm is used for particle measurement to automatically adjust the measurement results. Numerical intelligence is added to the algorithm to increase the accuracy of correction results. The research deals with the problem of matching the results of indirect measurements and the results of the control equipment. For data analysis, fertilizer diameter, mean diameter, aspect ratio, symmetry, sphericity, convexity and some other parameters are used. The mismatch of the artificial neural network results with the control equipment results is slightly higher than 1%.

Full textAbstract:
Current in-field methods for grading logs are based on visual rating scales, which are subjective, operator-dependent and time-consuming. Various wood defects such as knots, resin pockets, rot and compression wood, amongst others, affect the quality and potential usage of a log. Early detection of these defects and an adequate wood quality classification help to optimise resource use along the whole production chain. Therefore, the specific target for the development of an efficient in-field grading approach was defined within the project Integrated processing and controL systems fOr sustainable forest Production in mountain areas – SLOPE. The grading is conducted by means of automatic measurements of selected wood properties with diverse sensors, including near infrared (NIR) spectrometers. A series of studies was conducted on wooden discs using laboratory equipment and a portable NIR spectrometer. In-field measurements of standing trees and harvested logs were also performed using a portable instrument. Principal components analysis models for identification of log defects were developed using the spectra collected with both instruments. Such models will serve for the automated determination of quality indexes to be used for log grading. It is foreseen that the NIR-based quality indexes will be integrated with the expert system under development within the SLOPE project and combined with quality information derived from other sensors. The overall goal is to provide a reliable technology for automatic log quality grading in the forest industry.
