Holota Oleksandr Oleksandrovych. Research on the operating modes of the track structure control system of physical model of magneto-levitation transport. – Qualifying scientific work on the rights of the manuscript. The dissertation on competition of a scientific degree of the doctor of philosophy on a specialty 275 - Transport technologies (on kinds). - Ukrainian State University of Science and Technology, Dnipro, 2025. The dissertation is devoted to the issues of studying the operating modes of the track structure control system of a physical model of maglev transport. In this work, the definition of “track structure” refers to traction electromagnets that ensure the implementation of the following operating modes on the stand - levitation and crew traction of a physical model of maglev transport. The work covers both the theoretical and practical aspects of studying control systems for high-speed ground transport systems. Maglev transport is one of the most promising technologies for high-speed movement. Being a type of high-speed transport, maglev transport has the potential to significantly change the transportation of passengers and cargo compared to traditional high-speed railways due to the absence of wheel-rail contact. This factor makes it possible to provide higher operating speeds, less wear and tear on infrastructure elements, lower noise and vibration levels, and increased smoothness of movement. For passenger transport, this means reducing travel times over medium distances and competitiveness with air transport, and for freight – the possibility of fast delivery of goods with high energy efficiency. Today, several sections of this type of transport have been put into operation in the world. Shanghai Maglev (China) with a length of about 30 km, connecting Pudong Airport with the city, and Linimo (Japan) – an urban line about 9 km long. In addition, experimental or test sections have been implemented, including SCMaglev projects in Japan, demonstrating the possibility of achieving speeds of over 500 km/h. However, the construction of full-scale experimental sections is an expensive and complex process, which limits the widespread implementation of the technology on national transport system networks. Existing magnetolevation technologies are based mainly on long power sections and centralized control systems, which complicates experimental research, adaptation of operating modes and implementation of new control algorithms. An important stage of research in this area is physical modeling and creation of experimental stands, which allows reproducing the main processes of interaction between the crew and track coils, studying their electromagnetic parameters, checking control algorithms and evaluating the dynamics of transient processes. The use of such an approach provides the possibility of effective testing of modern element base and forms the prerequisites for further improvement of magnetolevation transport technologies and their implementation in full-scale systems of the new generation. The relevance of the work is due to the need to develop scientifically substantiated control modes for a physical model of a magnetolevation vehicle and corresponding control systems capable of ensuring stable movement and high speed during magnetic levitation. The result of the operation of the studied control system is the determination of the ranges of spatial angles for supplying control pulses to the track coils of the physical test stand of magnetic levitation transport.
