Abstract
The present work aims to analyze from a methodological and instrumental point of view the development of asynchronous motor propulsion systems. For this purpose, PWM and SVM modulation methods, FOC and DTC vector control techniques, as well as their advantages and disadvantages are described. The theoretical bases and functional schemes of FOC and DTC control are given, including the asynchronous motor mathematical model, similar to the direct current motor model. Special attention is paid to creating of a common meaning for describing the components operation equations of the traction system, equations that can be used for system modeling and simulation. The paper also refers to a series of modern voltage converters with vector control, which are produced by several companies in different countries and are intended for the control of three-phase asynchronous motors. The results of the study create a basis for research and development of traction systems with multiphase asynchronous motors for urban electric passenger vehicles.
