摘　　要：针对交流牵引电力机车在库内低速移动的工况,提出以机车DC 110 V蓄电池作为动力源,采用基于模糊自适应PI速度控制器的矢量控制系统。通过控制异步电机的转速,从而控制交流牵引电力机车在库内低速、稳定移动。最后,利用MATLAB/Simulink对本控制系统进行建模和仿真实验。仿真结果表明,基于模糊自适应PI速度控制器的矢量控制系统具有电压利用率高、转速误差及超调小、系统速度调节的自适应能力强等优点。Based on the operating mode of the stall parking of AC traction electric locomotives, a vector control system, with DC 110 V accumulator its power source, has been designed of a fuzzy self-adaptive PI speed controller. By controlling the rotational speed of the induction motor, a slow and steady movement of the AC traction locomotives has been realized in the process of stall parking. The final result of a modeling and simulation test for the control system based on MATLAB/Simulink shows that the vector control system based on the fuzzy self-adaptive PI has the following advantages：more efficient voltage utilization, less rotational speed errors and smaller overshoot, greater self-adaptive capacity for the system speed regulator, etc.
