    • A current collector for a railway trolley vehicle includes a current collecting member having a contact strip, a driving system for moving the current collecting member into and out of contact with a trolley wire, a load cell for detecting force acting between the current collecting member and the driving system, a displacement meter for detecting displacement of the driving system, first and second estimating circuits, and a control circuit. The first estimating circuit provides an estimated value of the contact force between the current collector and the trolley wire by estimating values of first parameters of the contact strip, the current collecting member, and the trolley wire and summing products of each of these values and a corresponding weighting factor. The second estimating circuit provides an estimated value of a disturbance suppressing force by estimating values of second parameters of the contact strip, the current collecting member, and the trolley wire and summing products of each of these values and a corresponding weighting factor. The control circuit calculates a difference force value by subtracting the estimated contact force value and the estimated disturbance suppressing force value from a contact force target value. The control circuit then adjusts a pushing-up force of the driving system on the basis of the calculated force difference value.
    • 一种用于铁路车辆车辆的集电器包括具有接触条的集流部件,用于将集电部件移动到与架空线接触和脱离接触的驱动系统;负载传感器,用于检测作用在集电部件和 驱动系统,用于检测驱动系统的位移的位移计,第一和第二估计电路以及控制电路。 第一估计电路通过估计接触片,电流收集构件和电车线的第一参数的值来估计集电器和电车线之间的接触力的估计值,并且将这些值中的每一个和 相应的权重因子。 第二估计电路通过估计接触片,集电构件和电车线的第二参数的值和这些值中的每一个的相加乘积和相应的加权因子来提供扰动抑制力的估计值。 控制电路通过从接触力目标值减去估计的接触力值和估计的扰动抑制力值来计算差分力值。 然后,控制电路基于计算出的力差值来调整驱动系统的上推力。
