Исследование системы управления двигателем постоянного тока с многоуровневым преобразователем напряжения

Abstract

The problem of regulation for a DC motor with multi-level DC-DC converter is discussed. The control system is considered consisting of two feedback loops. In the first one the armature current control for a DC motor is provided by means of pulse-width modulated control for multi-level DC-DC converter. In the second one DC motor speed control is maintained. Proportional-integral (PI) controllers are designed for armature current and motor speed control based on singular perturbation technique such that multi-time-scale motions are artificially induced in the closed-loop system. Numerical simulations are performed in order to show efficacy of the proposed design technique.

Обсуждается задача синтеза системы управления для двигателя постоянного тока независимого возбуждения с многоуровневым преобразователем напряжения. Рассматривается двухконтурная система подчиненного регулирования, которая содержит контур стабилизации тока цепи якоря и контур стабилизации скорости вращения двигателя. В качестве закона управления для каждого контура используется ПИ-регулятор, где расчет параметров регулятора выполнен на основе метода разделения движения.
