摘要

讨论了采用多级DC-DC变换器的电力机车直流电机调速控制器的设计问题，其中控制系统由两个反馈回路组成。第一种是通过对多电平DC-DC变换器的脉宽调制控制来实现直流电机电枢电流的控制。在第二种情况下，保持直流电机的速度控制。基于奇异摄动技术，在闭环系统中人为诱导多时间尺度运动，设计了电枢电流和电机转速的比例积分(PI)控制器。数值模拟是为了证明所提出的设计方法的有效性。

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

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.
