摘　　要：在机车牵引控制系统中,是通过粘着控制实现车轴牵引转矩的控制。在传统的粘着控制方法中,由于不同路况下控制参数固定会导致机车牵引力损失过多,为优化轮轨间的粘着利用,提高机车的牵引力,提出了一种模糊路况识别的粘着控制方法,通过观测器观测到的粘着系数以及机车车轴参考速度估算模块计算的蠕滑速度模糊识别机车的运行路况,根据不同路况调整相应的空转判别参数以及牵引转矩输出函数。建立电力机车模型来验证方法的有效性,仿真结果表明,改进的粘着控制方法减少了牵引力的损失,提高了粘着利用效率,为电力机车的牵引运行提供更高的牵引力。The adhesion control is one of the difficult problem for locomotive traction control systems. In traditional adhesion control methods,the fixed control parameters of locomotive cause much locomotive traction loss. To optimize the adhesion utilize and the traction of locomotive,an adhesion control method which is based on the fuzzy road identification is proposed. The method identifies the road condition of locomotive by adhesion coefficient,which is estimated through the disturbance observer,and the difference value of locomotive axle reference velocity and axial velocity. The method switches the idling discriminant parameters and the output function of traction torque. The simulation model of electric motor coach is established to verify the effectiveness of the method. The simulation shows that traction loss can be reduced by the method,and the method can improve the using of adhesion.
