An open-loop anti-swing control device for a bridge crane comprises a crane controller, a trolley electric dragging system and a large vehicle electric dragging system, wherein the trolley electric dragging system and the large vehicle electric dragging system respectively convert a trolley preset speed signal and a large vehicle preset speed signal sent by the crane controller into a trolley given speed signal and a large vehicle given speed signal with an anti-swing effect through a time delay filter and a frequency converter, and a trolley motor driving voltage and a large vehicle motor driving voltage are obtained according to the trolley given speed signal and the large vehicle given speed signal so as to drive a trolley motor and a large vehicle motor. Due to the fact that the trolley given speed signal and the large vehicle given speed signal have the anti-swing effect, load swing of the bridge crane is restrained.

    一种用于桥式起重机的开环防摇控制装置,包括起重机控制器、小车电力拖动系统和大车电力拖动系统。其中,小车电力拖动系统和大车电力拖动系统分别通过时滞滤波器和变频器将起重机控制器发送的小车预设速度信号和大车预设速度信号转化为具有防摇效果的小车给定速度信号和大车给定速度信号,以依据小车给定速度信号和大车给定速度信号获取小车电机驱动电压和大车电机驱动电压,来驱动小车电机和大车电机。由于小车给定速度信号和大车给定速度信号具有防摇效果,从而抑制桥式起重机的载荷摆动。
