摘要(Abstract)：

针对高速铁路牵引网低频振荡造成动车组牵引封锁的现象,提出了一种基于滑模控制的动车组网侧整流器控制策略。首先,推导了CRH5型动车组网侧单相整流器在dq旋转坐标系下的状态空间数学模型;其次,详细论述了控制策略原理和设计过程,包括外环电压滑模面与内环电流控制率的求取;最后,在Matlab/Simulink与RT-LAB平台上搭建了基于滑模控制器的双重化仿真模型,并与传统线性比例积分(proportional integral,PI)控制策略以及两种对比于PI控制响应性能更好的新型控制策略:基于互联和阻尼分配的无源控制(无源控制)和基于模型的预测电流控制控制(预测控制)的仿真试验效果进行了比较,结果证明滑模控制具有更好的动、静态特性。为进一步验证滑模控制对低频振荡的抑制效果,搭建了基于滑模控制与PI控制的多车接入的车网耦合系统仿真模型,仿真结果证明滑模控制可以有效地抑制低频振荡的发生。
