基于机车四象限变流器的直流偏置抑制方法研究
|
摘要
介绍了机车四象限变流器的工作原理、控制方法和交流侧电流存在直流偏置的原因,讨论了2种常用的抑制直流偏置的方法。通过理论分析,给出了一种通过根轨迹法对控制器进行设计优化,实现对电流直流偏置抑制的控制算法。经过Matlab/Simulink软件的仿真分析和半实物仿真平台测试,表明该控制算法具有良好的抑制效果,满足设计需求。
Working principle, control method of locomotive four quadrant converter and the cause of DC bias in AC side current were introduced. Two common methods to suppress DC bias were discussed. Through theoretical analysis, a control algorithm for DC bias suppression was presented, which optimized the controller design by root locus method. The simulation analysis of software Matlab/Simulink and the test of hardware-in-the-loop simulation platform showed that the control algorithm has good suppression effect and met the design requirements.
