摘要
机车的黏着是有轨运输系统的基本条件,提高机车黏着性能是一个至关重要的课题。介绍了黏着的基本理论,黏着控制的目标就是在机车运行过程中,通过对驱动力的控制,使实际的黏着系数尽量逼近于当时路况的黏着系数最大值,从而获得最大的平均牵引力。对现有主要的机车黏着控制方法(反馈与极值组合法、模型控制法、模糊神经网络法、模糊控制及其他控制方法)作了简要总结,介绍各种方法的理论基础和控制模型,比较其性能的优劣,指出模糊神经网络和模糊控制法是两种很有前景的控制方法。
Locomotive adhesion is an important factor of rail transport system.It's an very important subject to improve the locomotive adhesion capability. This paper introduces the basic theory of adhesion. The aim of adhesion control is to make actual adhesion coefficient approach to the maximum adhesion coefficient of the wheel - rail by controlling the drive force to get the appropriate traction force in average. The locomotive adhesion control methods (including Hybrid Slip Control Method, Model Based Controllers, Fuzzy Nuro Net controller, Fuzzy Logic Slip Controllers and other methods) are summarized, which theories, control models, advantages and disadvantages are introduced.As a result, the Fuzzy Neutral Net controller, Fuzzy Logic Slip Controllers are pointed out better control method than others.
