RESEARCH OF CONTROL MODES OF THE TRACK STRUCTURE OF A PHYSICAL MODEL OF MAGLEV TRANSPORT

Purpose. The purpose of the study is to develop and experimentally verify the characteristics of track coils and the performance of the positioning system of a physical model of a magnetic levitation (maglev) transport system with a modular track structure. Such a system reproduces the main elements of high-speed maglev, in particular a moving platform (maglev vehicle) with permanent magnets and track modules with inductive coils, which receive a control pulse.Methods. A comprehensive approach was applied, including theoretical analysis and systematization of the current state of magnetic levitation transport, the development of an experimental physical stand taking into account physical modeling, the use of software and hardware complexes based on Arduino for current control and positioning, experimental measurements of coil inductance and their characteristics, a study of the idle mode of the physical model, as well as the development and testing of adaptive control systems and maglev vehicle movement coordination algorithms. Results. A physical model with a modular structure was created and tested, experimental data on the inductance of the track coil were obtained, a system of sectional positioning of the crew using sensors and an encoder was developed, the principles of applying adaptive traffic control systems were implemented, and algorithms for sequential coordination of the work of sections of the track structure were developed. A study of transient processes and principles of operation of traction modules was carried out, which can further contribute to improving the energy efficiency of the system. Scientific novelty. For the first time, data on the operation of track coils at different signal frequencies in a physical model of such a configuration have been systematized, which will have an impact on further calculations and research of experimental models of maglev transport. Practical significance. A physical model of a magnetically levitated transport system with a modular structure was created, which allows the electromagnetic interaction to be studied in conditions close to real ones. A special feature of the physical model is the introduction of a sectional crew positioning system based on an encoder and a Hall sensor with a reactive principle of control pulse supply. The results obtained can be used in the future to improve magnetic levitation transport control systems, ensure sectional and modular positioning accuracy. The proposed approaches can be used to build and develop physical models. This will allow implementing innovative solutions in the field of high-speed ground transport.
