MODERNIZATION OF ADVANCED TRANSPORT TECHNOLOGIES TO ENSURE SUSTAINABLE SOCIETAL DEVELOPMENT

Abstract

Introduction. Contemporary trends in transport development emphasize increasing energy efficiency
while simultaneously reducing adverse environmental impacts.
Problem Statement. Existing magnetic levitation (maglev) systems retain a number of legacy (“historical”) design features that constrain their energy efficiency and limit the precision of traction linear motor control, etc.
Purpose. This study aims to develop an inertia-free control system for the traction–levitation system of a maglev vehicle that integrates the advantages of both electromagnetic and electrodynamic suspension methods and operates using an environmentally sustainable energy supply.
Material and Methods. The study draws upon theories and methods from electric traction, electrical machines, electrical engineering, power electronics, and automatic control theory. These approaches are applied to redesign the architecture and parameters of the power supply system, traction linear motor, levitation subsystem, and control strategies governing traction and suspension.

Results. The findings have demonstrated that substantial improvements in maglev technology can be achieved through the coordinated integration of electromagnetic and electrodynamic levitation methods within a fundamentally new system architecture. Specifically, the conventional “long-stator” track design with continuous three-phase windings is replaced by discrete modular units capable of dynamic electronic reconfiguration. This approach enables flexible reconfiguration of the operating modes of module coils according to a specified control algorithm, with energy supplied exclusively to those coils aligned with the projection of the maglev vehicle onto the guideway. The system’s energy efficiency is enhanced through localized power supply to standardized modules from a distributed network of photovoltaic converters.
Conclusions. The study has substantiated a second-generation traction–levitation system concept based on the
synchronized application of electromagnetic and electrodynamic levitation principles. The proposed approach enables the generation of both lift and propulsion forces using standardized modular units operating in different modes under coordinated control.
