    摘 要:为提高电力机车的稳定性和调节系统的快速性,优化面对突发情况时的抗扰控制性能,提出了一种逆变器抗扰控制策略。将自抗扰控制器置于速度环中,来代替矢量控制中的 PID 控制器,使用自抗扰控制技术能够改善电力机车的动态响应,优化对逆变器的控制效果。在理论基础上完成基于某八轴机车实际参数的离线仿真和半实物仿真,验证了此抗扰策略的优化效果,极大地缩短了机车调速的过渡时间,降低了超调量,增强了鲁棒性并减小了稳态误差。

    Abstract: In order to increase the stability of electric locomotives, the speediness of governing system and the performance of disturbance rejection in case of emergencies, the paper proposes the disturbance rejection control strategy for inverters. In the paper, the auto disturbance rejection controller is placed in the speed loop to replace the PID controller of the vector control. The auto disturbance rejection control technology is able to improve the dynamic response of electric locomotives and optimize the control effect of inverters. Then, the off-line simulation and semi-physical simulation of an eight-axle locomotive’s actual parameters are completed on the theoretical basis to verify the optimization effect of this disturbance strategy. It is found that this strategy shortens transition time of the locomotive speed regulation, reduces the overshoot, enhances the robustness and decreases the steady error.
    Key words: electric locomotive; inverter; disturbance rejection control; semi-physical simulation
