In this article, we consider the problem of studying the dynamics of linear objects with variable delay based on graph models. The output signal of the variable lag element is deformed along the time axis. The function that is the output of the rung will be either "compressed" or "stretched" on the time axis relative to the input function. Conditions for the physical realizability of an element with a variable delay are given. The physical properties of the variable delay element and the generality of individual stages in the formation of models of systems with constant and variable delay are taken into account. A linear variable delay system can be studied using matrix equations. On the basis of the graph model, relations are obtained for calculating processes in a linear system with variable delay. The graph model of the system makes it possible to bypass laborious calculations and to exclude operations associated with insufficient matrix density. The above scheme can also be used to calculate processes in variable delay systems in the control channel.

Currently, unmanned control systems for various vehicles, including cars, are widely used. Driving an unmanned vehicle involves solving tasks related to recognizing road objects. An improved algorithm for solving the problem of detection and recognition of round traffic light signals is proposed. To solve this problem, we use: fast radial symmetry transformation, Hough transform, and color segmentation. A special feature of the algorithm is that the areas where the light signals are located they are preliminarily determined based on the color attribute, followed by specifying the shape and position of objects. At the final stage, the solution is refined using the Hough method. The proposed algorithm has shown operability, it can be expanded in terms of the types of recognized signals and applied as part of unmanned vehicle control systems, as well as part of driver assistance systems for solving problems related to the prevention of dangerous and emergency situations.

In this paper, we study properties of the receding horizon optimal FIR (RHOFIR) filter. The used approach based on analysis its error covariance matrix (ECM). Our contributions are as follows. First, the monotonicity and convergence of the ECM with increasing the horizon size of the sliding window (SW) are established. One important consequence of obtained results is that the ECM trace of the RHOFIR filter does not reach its lower bound (a steady state) on compact sets. This allows formulating a rule for selecting a horizon size of the SW determining a moment when the ECM trace enters a neighborhood of the steady state. Second, an upper bound is obtained for the decomposition of the ECM into two terms in which one of them does not depend on the noise of the dynamics. This makes it is possible to specify an estimate for the horizon size of the SW using information only about the noise intensity of the measurements. Third, an error sensitivity analysis to the dynamics and measurements noises of the ECM is carried out.

The models that are part of the FMSP cover the main and a number of auxiliary technological systems of the power unit, automatic control systems. The developed flexible modeling software package is designed to simulate dynamic processes occurring in NPP power units with VVER-1000 reactors. The FMSP allows considering various types of violations in the operation of safety systems and energy imbalances in the reactor core. The results of verification of a flexible modeling complex based on stationary neutron-physical calculations of the VVER-1000 reactor core using the BIPR-7 program and NPP operational data are presented.

The use of classical frequency converters with the complex control system allows us to smoothly adjust a wide range of the motor speed with maintaining the stiffness of the mechanical characteristics. This converter is based on using semiconductor devices to control a single-phase asynchronous motor. The developed frequency converter has a low cost and simple design compared to previous frequency converters.

The authors pay attention to the monitoring technologies development for complex technical systems. Such systems include many heterogeneous moving and stationary objects. The systems are equipped with both built-in and external means of technical diagnostics and monitoring, which form informational messages about the measurement results and the current state of the components. This information allows service personnel to promptly prevent a shutdown of the process and identify subcritical conditions. This increases the fault tolerance of the objects being diagnosed. When organizing systems for technical diagnosis and monitoring, it is often impossible to provide the necessary completeness and depth of diagnosis for making an accurate diagnosis and subsequent forecasting. However, the obtained information allows the formation of many diagnostic features inherent in the states of the objects being diagnosed. This information may be the source for the implementation at the software level of decision support subsystems by service personnel operating diagnostic objects. To form the initial data for decision support subsystems, the authors proposed to use the following data: data from measuring subsystems, historical data about the diagnostic object, statistical indicators from monitoring systems in automatic mode. As statistical indicators, the probabilities of occurrence in the various components of object defects and data on the diagnosing implementation costs are used. These data vary depending on the service life, the diagnostic object importance for the process, its effect on the system readiness, etc. The source data is used at the software level for the diagnostic algorithm’s implementation in the questionnaires form. The questionnaire is a tree-based weighted oriented graph. The output contains the recommended sequence of operations for testing the diagnostic object. That allows you to achieve the most effective localization of the defect. An example of the technologies developed for monitoring critical facilities from the railway automation field is given.

The state and operation quality of sets of submersible electrical equipment (SEE) at oil wells as a complex engineering system depends on the fault-free and reliable operation of downhole equipment components. Oil production SEE, especially submersible electric motors (SEM) are subjected to various external factors and impacts and they are used in various operating modes. To obtain the data on the state of SEE, we used statistics for the failures during operation. This valid method for the analysis of the conditions of the engineering facilities in the industry is, in most cases, the only suitable one for the mathematic functional and quantitative description of reliability, including the SEE cycles to failure parameter. We collected and analyzed the data on technological failures at oil production facilities and established a database for relevant statistics on the use of SEE (for 2014-2019). We present the results of the statistical analysis for the correct representation of the current conditions of the SEE (including SEM). We used them to produce a systematized assessment of the current state of SEM using smart analysis and probabilistic statistical modeling. We identified and ranked the factors resulting in technological failures, formulated a set of technical and organizational actions to minimize them, and improve the reliability and operation readiness of the SEE.

The problem of detecting, recognizing and predicting anomalies has appeared relatively recently. However, when solving this issue, a number of difficulties arise, mainly associated with the need to take into account and detect previously unknown types of attacks and impacts. The resolution of this issue immediately attracted the attention of specialists in the areas of network security and information and industrial systems. Consequently, the existing solutions to some of the simplest particular cases of solving the issue of recognizing anomalies in computational processes did not allow the development of some unified, comprehensive method for detecting previously unknown types of attacks and influences. To address this issue, Western and Russian research teams and schools urgently engaged in in-depth abstract study of this issue. The detection of anomalies in dynamic information flows largely determines the effectiveness of information security management of computer networks in information and industrial systems. At the same time, the technology for predicting dynamic flows, data plays a major role in the concept of anomaly detection systems in the protection of information of various APCS. The creation of each automated system is based on the future capabilities of computer technology, advances in control theory, mathematical modeling and optimization methods. It is proposed to use the technology of opto-ultrasonic transmission and reception of information. Under ultrasonic ultrasonic waves (acoustic signals). The main source of acoustic signals are electromechanical ultrasonic vibrating systems. In this work, information leakage through a technical opto-ultrasonic channel is understood as the uncontrolled use of information from the protected information carrier through the physical medium to a technical means that intercepts information. Depending on the physical nature of the occurrence of information signals, the medium of their propagation, the technical channels of ultrasonic information leakage can be divided into acousto-vibration (vibration), acousto-optic (laser), acoustoelectric and acoustoelectromagnetic (parametric). Within the framework of this article, acousto-optic (laser) technologies are investigated.

Currently, there is an active development of new frequency ranges (millimeter and submillimeter parts of the spectrum) due to the introduction of the 5G standard and the study of 6G networks. This leads to the fact that there is a need to develop flexible antennas for these frequency ranges. It is advisable to use graphene for these purposes, since it is possible to manufacture environmentally friendly flexible antennas on its basis. In this work, the authors aim to determine the minimum and maximum frequencies for which flexible graphene antennas can be fabricated using various graphene deposition technologies.The paper presents a comparative analysis of the possibility of using various technologies for deposition of graphene for the manufacture of antennas in the millimeter and submillimeter frequency ranges. To perform this analysis, a critical size parameter was introduced. On its basis, the minimum and maximum frequencies for which flexible graphene antennas can be fabricated are determined using the considered graphene deposition technologies.The design and characteristics of a graphene eco-friendly dipole antenna on a paper substrate, which is made using screen printing technology, are presented. An assessment of the applicability of the technology used for the manufacture of elements of the Internet of things operating in the 5G millimeter frequency range has been carried out.
