Dc motor speed control for electric locomotive equipped by multi-level DC-DC converter

Abstract

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