Abstract

A method for compensating boom deflection comprising: determining a joint angle set of a boom if an end of the boom were to reach a predetermined target position when viewed as a rigid body, wherein the joint angle set comprises an angle of each joint of the boom; determining an actual position that the joint angle set causes the end to reach; determining the deviation between the actual and predetermined target positions; and when the deviation does not satisfy a predetermined condition, continuing to adjust the joint angle set until the deviation satisfies the predetermined condition. The end of the boom can consequently more accurately reach the predetermined target position. The present invention further relates to a method for controlling a boom, an apparatus for compensating boom deflection, an apparatus for controlling a boom, a construction machine, and a computer-readable storage medium.
