Due to competition in the global market, Russian mining enterprises are striving to improve their technical equipment and energy efficiency. Improvement of electric drive systems of mechanisms involved in mining can lead to significant results in solving this problem. In this regard, much attention is paid to the development of more advanced devices used in the electric drive. Currently, various devices for starting, operating and regulating the speed of three-phase squirrel cage induction motors are being developed. To check the performance of the developed devices, a variety of research methods are used, one of which is computer simulation. The article discusses an original adjustable transistor gearbox for a three-phase squirrel cage induction motor powered by a DC power. The urgency of using a semiconductor converter in drives of mechanisms of mining enterprises has been substantiated. To study the operation of the motor in the environment in the Matlab Simulink environment, a simulation model of the developed drive was created. To analyze the characteristics of an induction motor when working with a semiconductor converter, they were compared with the natural mechanical characteristic.

The article presents a DC power supply system based on a contactless synchronous generator with combined excitation and an uncontrolled rectifier. One of the possible options for constructing a DC power supply system for autonomous objects is described. In particular, such a power supply system can be used as an on-board power supply system for aircraft. A synchronous generator with combined excitation replaces three-stage synchronous generators, as an electric generator on board aircraft. The working magnetic flux in such a generator is created from two sources of magnetomotive force - a permanent magnet and an excitation winding. The main, as a rule, most of the working magnetic flux is created by permanent magnets, the excitation winding creates an additional, as a rule, smaller part of the flux than provides a change in the total flux and regulation in a certain range of the output voltage of the generator. Scenarios for selecting parameters and controlling a synchronous generator that ensure the stability and controllability of the system are proposed and investigated. The results obtained can be useful in the development of power supply systems for aircraft and autonomous objects.

This paper discusses the use of modified permanent magnet synchronous generators in order to improve the controllability of the system and increase the range of operating parameters. A mathematical description of the process of operation of a power supply system built using Smart-grid technology with distributed generation, where each generating cell is a whole generating complex, which must provide the required voltage level and control of the flowing current, is presented. The work of a simulation model of an electric power supply system with a single generating complex, with control functions of an aperiodic type, is considered. The boundaries of the system parameters were established and the key indicators of the transition process and the accuracy of the system operation were evaluated. Recommendations are also formulated for further improvement of the system, which will be aimed at improving the quality indicators of the transition process of nodes and the whole system.

Many modern high-speed wireless data transmission networks, digital television, mobile networks and other often use OFDM multifrequency signals to resist a multipath propagation. However, the use of OFDM, in addition to its advantages, faces a number of problems. Due to the fact that the transmission path, reception path and the physical channel can often have the non-linearity, the OFDM signal at the transmission path output will have crosstalk. This article analyzes the signal reception noise immunity with crosstalk in system with OFDM and non-linear path amplitude characteristic. Crosstalk between OFDM subcarriers can significantly reduce the noise immunity of the transmission system. Dependence of the error probability, taking into account crosstalk noise, on the ratio of the average signal powers to the fluctuation noise is analyzed. It is also shown that limiting the peak values of the OFDM signal in the transmitter allows to obtain an energy gain compared with the linear mode of the transmitter.

The problem of the synthesis of a film attenuator, performed by applying an absorbing material to the conductor, is considered. The absorbing material has a parameter of maximum dissipated power per unit area, then when synthesizing an attenuator to attenuate high powers, the problem of exceeding the maximum dissipated power per unit area may arise. A sectional attenuator structure has been proposed, which is a set of sections having different attenuation to reduce the power dissipated per unit area. An algorithm for the synthesis of a sectional attenuator is proposed. The attenuator sections are rectangles of various widths. The attenuation distribution is performed using the Taylor series expansion of mathematical functions. The properties of the functions are considered in relation to the problem of the attenuation distribution in the attenuator. The graphs of the dependence of the power depending on the attenuator section are plotted. Power distribution has been confirmed by simulation results. Theoretical calculations were confirmed by simulation results in CST Microwave Studio software.

The widespread use of virtual reality in recent years has offered researchers many new directions for research and development. One of the most important and obvious industries for the application of VR from the very beginning was education. Educational applications for VR are quite common today. The degree of immersion in the environment offered by VR, according to many authors, has a positive effect on the perception of information provided in applications. Another current trend in connection with the COVID-19 pandemic is the active transition of many institutions to distance or mixed learning. However, there are currently very few VR applications for distance learning. This article describes the possible format of such a system, as well as the requirements for it. Various aspects of the proposed system, such as financial, network, and technical, are considered. In particular, the necessary computer configuration and network parameters are described. The issues of the user interface and user security are touched upon. Possible approaches to solving these problems are proposed.

The work is devoted to assessing the influence of the electrophysical parameters of the electret on the electromechanical characteristics of the variable capacitor with a built-in charge. A model of the variable capacitor with a built-in charge is considered and mathematical expressions are obtained to estimate the maximum possible parameters of MEMS: the critical displacement of the movable electrode, the magnitude of the external voltage and the electret surface charge density. It is shown that the critical displacement of the movable electrode with constant parameters of the dielectric layers and the increasing charge of the electret doesn't change, while the maximum allowable value of the external voltage decreases monotonically. It has been found that as the thickness of the dielectric layers, or their relative permittivities increase the maximum allowable displacement of the movable electrode, the built-in charge, and the applied external voltage also increase. As a result, the internal field of the electret as well as the energy stored by the variable capacitor which is necessary for performing useful work rise too. It has been observed that during the converter assembly process external factors can lead to a significant decrease of the electret effective voltage.

At the present stage of the technology development, the reliability indicators of technical systems have increased, while the person reliability began to recede over time, therefore increasing the role of the subjective factor in the emergence of industrial accidents and incidents. In order to reduce the risk of damage made by the subject, the admission to the performance of professional tasks should be multistage and periodic (continuous). Accidents can be the consequence of subjects staying in “inadequate” psychophysiological state: alcohol intoxication, stress, drowsiness, etc. In this work, the authors offer a neuro-Bayesian algorithm for recognizing psychophysiological states of subjects using facial thermographic images, based on the use of convolutional neural networks committees and sequential application of the Bayesian hypothesis formula. More than 97% of the recognition accuracy of seven psychophysiological states has been achieved for a 10 second monitoring period, which exceeds the known world indicators both in accuracy and recognition duration.

The paper proposes the computational algorithm for solving the inverse problem of exploratory gravimetry, consisting in the separability of two isolated bodies that generate anomalies of the measured magnitude of the gravitational force. It is based on the use of the results of multi-level measurements of the gravitational field vertical component. The obtained data of gravity measurements at two levels are converted into numerical values of the gravitational field strength in directions (azimuths). It allows to solve the inverse localization problem for isolated inhomogeneities. This article presents a numerical method for solving the isolation problem. An algorithm for solving the problem of separability of bodies with excessive density is proposed, based on the method of finding the sum of the vectors of the gravitational field strength along the azimuths of the directions between points at two levels of gravity measurement. The vectors of balancing directions determined in this way give a qualitative solution to the inverse problem of separability of test bodies. The quantitative characteristics of inhomogeneities are refined by varying the position (geometric parameters) of the test bodies, as well as the densities of the host rocks and bodies that generate gravitational anomalies. Minimizing the norm of the residual functional of empirical data - the results of stratified measurements and calculated values of the gravitational force for varied data at the measurement levels gives a quasi - solution - the parameters of the optimal location of the test bodies of the assumed shape.
