Abstract
A controller includes a drive part, a posture information acquisition part, and a control part, the control part calculates a gravity center velocity of a working device on the basis of posture information about the working device detected by the posture information acquisition part and calculates a target gravity center velocity being a target value of the gravity center velocity on the basis of a difference between a grounding work to be exerted to the ground by the working device and a target grounding work, and provides a feedback correction to an instruction signal to make the gravity center velocity approach the target gravity center velocity and inputs the corrected instruction signal into the drive part.
