The paper considers development of new electric drive systems based on an induction motor with a wound rotor having improved performance by introducing new circuit solutions and control algorithms that provide motor control via the rotor circuit. Research results: the principle of operation of the induction resistance, introduced into the rotor circuit through a frequency converter, changing its parameters depending on the frequency of the current flowing through it, is described. A method for controlling the speed of the electric motor, which consists of a smooth change of the additional inductive-active resistance introduced into the rotor circuit connected to the rotor through a frequency converter, is proposed. The technique reduces to the rotor winding resistance and induction resistance to the DC link is applied. The efficiency test of the proposed electric drive system in the software package MatLab Simulink through the method of mathematical modeling is performed. On the basis of computer simulation mechanical and power characteristics of the described electric drive system were obtained. On the grounds of the data obtained as a result of modeling the properties of the electric drive system are studied. © 2019 IEEE.

Progressive LiDAR Adaptation for Road Detection

Despite rapid developments in visual image-based road detection, robustly identifying road areas in visual images remains challenging due to issues like illumination changes and blurry images. To this end, LiDAR sensor data can be incorporated to improve the visual image-based road detection,because LiDAR data is less susceptible to visual noises. However,the main difficulty in introducing LiDAR information into visual image-based road detection is that LiDAR data and its extracted features do not share the same space with the visual data and visual features. Such gaps in spaces may limit the benefits of LiDAR information for road detection. To overcome this issue, we introduce a novel Progressive LiDAR adaptation-aided road detection(PLARD) approach to adapt LiDAR information into visual image-based road detection and improve detection performance. In PLARD, progressive LiDAR adaptation consists of two subsequent modules: 1) data space adaptation, which transforms the LiDAR data to the visual data space to align with the perspective view by applying altitude difference-based transformation; and 2) feature space adaptation, which adapts LiDAR features to visual features through a cascaded fusion structure. Comprehensive empirical studies on the well-known KITTI road detection benchmark demonstrate that PLARD takes advantage of both the visual and LiDAR information, achieving much more robust road detection even in challenging urban scenes. In particular, PLARD outperforms other state-of-theart road detection models and is currently top of the publicly accessible benchmark leader-board.

This paper discusses a smart laboratory robotics system designed to allow students remote connection and work with robotic manipulation devices and applications, as well as for teaching and conducting collaborative research projects in the field of electrical engineering and automation. A scheme of connecting all the necessary robotic devices and video cameras to the main server in the laboratory for the possibility of connecting to a remote desktop is presented. The developed solution for remotely connecting students to a physical robotic cell, which is connected to the lab server, is presented. Thanks to the proposed system, it was possible to conduct a debugging of new solutions for the control of robotic manipulation systems on a particular connected technological equipment. A telepresence system with real-time video streaming of physical robotic cell was developed to monitor the behavior of the robotic system remotely in order to understand the process of the connected devices clearly after the solution was uploaded to the robot controller. © 2022 IEEE.

Grid synchronisation is essential for grid following inverter control. Typically, a phase-locked loop (PLL) is used to perform the synchronisation, but it is known that the PLL can fail to synchronise with the grid in weak grid scenarios. Although there have been many studies on this topic which relate the grid impedance, the grid voltage and the PLL parameterisation to the grid synchronisation, comprehensive analyses are difficult due to the nonlinear nature of the underlying system. Therefore, the exact relationships remain unclear. This paper investigates the stability of PLL-based grid synchronisation for a grid-side inverter with LC-type output filter and RL-type grid impedance. An analytical steady-state solution is presented, which is used for linearization and evaluation of the small-signal stability. Additionally, the transient stability with consideration of nonlinearities is investigated and a condition for stability of the PLL-based grid synchronization in the transient case is derived. The results are validated by numerical simulations. © 2023 IEEE.

The measuring test lead is an important part of high voltage bushings with capacitor-type insulation. The test lead is connected to the outer capacitor lining of the frame, dividing the input capacitance into two: C1 (pipe - last outer lining of the frame) and C3 (last outer lining of the frame - flange). For diagnostics of the in service condition of the input, it is sufficient to measure the insulation resistance R3, the capacitance C1 and the dissipation factor tgδl. The measured and corrected value tgδ1 is compared with the data of the acceptance test report. In the delivery condition, the obtained value tgδl should be close to the nameplate value. A significant difference of more than 3% between the capacitance value C1 and the value specified in the acceptance test report may indicate damage during transportation or installation, so that the input must not be put into operation. The value of the capacitance C3 depends on how the input is integrated. The article deals with the method of measuring the insulation parameter C3 at the installed, faulted line bushings. The confirmation of the normal contact of the outer lining of the hulls of the already installed line bushings is obtained. The conclusion contains conclusions on the results of measurements and recommendations to the equipment manufacturers to make changes in the operating manuals of the bushings. © 2024 IEEE.

The paper presents the design and analysis of a simulation model of the motion of a four-wheeled robot with a shock-absorbing chassis on a plane with the right pair of wheels on the ramp, drive on it and drive off the ramp and derive plots of the bending force acting on the upper suspension arm, force in the spring, moment on the rear wheel, angles of rotation of suspension hinges, speed of the cart and suspension levers on time. It was required to verify the coefficients of spring stiffness and spring length at rest from the spring calculation by the condition of locating the upper suspension arm perpendicular to the side surface of the robot when the robot is on the plane without external forces and torques, as well as by the condition of reducing the clearance of the robot. Based on the calculated forces for the suspension arms, a cross-section for the suspension arms is selected and their strength is calculated for the subsequent design of the physical robot. © 2022 IEEE.

Logic representation of programs gives an expressive way to perform analysis and transformation. Logic representation conforming to a specified metamodel enables analysis and transformation at both meta and concrete representation levels. Logic representation mapping rules express how programs can be automatically translated into metamodel conforming logic representation. The designed formalisms are suitable to any programming language. © 2010 IEEE.

The creation of energy-saving AC electric drives is an urgent task for the modern production. Most electric drives of general industrial mechanisms are equipped with asynchronous squirrel-cage motors, which are powered by frequency converters. At the same time, a number of production mechanisms are equipped with asynchronous motors with a phase rotor (cranes, ball mills, some types of conveyors and turbo-mechanisms). The beneficial use of slip energy and its return to the mains supply or to the stator circuit of the engine can increase the efficiency of the electrical installation. This is typical for circuits based on asynchronous valve cascades. As part of the modernization of electric drives, it seems appropriate to develop hybrid circuits based on frequency control circuits and cascade electric drive circuits, their control system. Mathematical modeling of electric drives of this type will allow analyzing the static and dynamic characteristics of the given modes of their operation. © 2020 IEEE.
