Tractional Electric Drive with Non-Sensing Element Vector Control System

Abstract

The purpose of the paper is a structure formation and an analysis of non-sensing element vector control system developed for tractional electric drive with the help of mathematical simulation method. The paper presents a functional diagram of the electric drive with non-sensing element vector control system operated by an asynchronous short-circuited electric motor. Main expressions used for evaluation of variables of system conditions and parameters are cited in the paper. The paper provides results of mathematical simulation method for electric drive system taking into consideration various parameter values which confirm serviceability of the developed control system within the whole range of possible parameter chnges.
