Алгоритм керування DC-DC перетворювачем для пристрою ослаблення поля

Abstract

Пропонується алгоритм керування DC-DC системою ослаблення поля тягових двигунів змішаного збудження. Наведені структурна схема DC-DC перетворювача та функціональна схема алгоритму керування. Задача виконується за допомогою мікроконтролера, а також ряду допоміжних датчиків, зокрема датчиків струму, температури, обертів, напруги, тощо. Система розглядається на прикладі тролейбусу ЗІУ-9 з резистивно-контакторною системою керування. In order to improve the energy efficiency of rolling stock and its characteristics are taken Various regulatory tools. In particular, improving circuit design, the transition to pulse traction motor control system, the use of key semiconductor devices with lower internal losses, and so on. Field weakening mode traction engines is one of the main modes of the electric rolling stock. In the previous article, the authors were reviewed in detail to improve the system weakening of the field using DC-DC converter. Grounded all the advantages and disadvantages of this method of regulating the excitation DC machine, but not raised the question of control system, including the algorithm, respectively, which should be easing off. The article rozlyanuto structural and functional scheme of the system weakening control field. The following table of correspondences values and sensors DPHP DPRK and DPRK matching values and α ust. Conclusions on the results.
