Abstract

An adjusting and control method of a swing resistance enhanced bridge-type carne comprises the following steps: step one, constructing an error signal; step two, determining a control target; step three, determining a control discipline; and step four, realizing the control method. The method can greatly improve the trolley transportation speed and effectively eliminate the swing of loads, thus improves the work efficiency and safety of the whole system, and has a very important practical application meaning.

Description

technical field [0001] The invention relates to an adjustment control method for automatic control of an underdriven bridge crane, in particular to an adjustment control method with enhanced anti-sway function. Background technique [0002] As a convenient means of transportation, bridge cranes are widely used in workshops, docks, ports and other places. The entire transportation process of the crane can be divided into three stages: 1. Lift the load to a certain height to avoid collision; 2. Transport the load to the target location safely and quickly; 3. Lower the load to the target point. Among them, the horizontal transportation process is the most challenging stage, because not only must the load be transported to the target position quickly and accurately during the transportation process, but also it is necessary to ensure that the load swing caused by inertia during the transportation process is as small as possible. Overhead cranes have been widely used because of ...
