| 摘 要： | 结合TA0649D机车牵引电机的结构参数，首先建立了该直流电机的数学模型，设计了该电机的转速，电流双闭环系统。在此基础上，通过故障(如绕组匝间短路与对地短路)模拟，利用递棼最小二乘法计算故障发生后电机绕组电阻的变化。仿真计算结果表明，所设计的参数识别法一递推最小二乘法是有效的，具有实际应用价值。

| Abstract: | Combined with the structural parameters of TAO649D traction motor, the mathematic model of the DC motor is built and its speed and current dual-closed-loop system is designed. Through the failure simulation, such as the inter-turn short circuit and grounding short circuit, the change in the winding resistance after the failure occurrence through the evolving minimum secondary multiplication method. The simulation result show that the designed parameter identification method, the recurrent least square method, is efficient and practical. |
