Slewing stop control apparatus and method for slewing type working machine |
摘要 |
A slewing stop control apparatus and method, capable of executing, while performing the control of determining the target slewing velocity based on a remaining slewing angle from the actual slewing motion position up to the slewing stop angular position, an automatic control of re-slewing the slewing structure having been stopped before the slewing stop angular position. The apparatus executes slewing angular velocity control for deciding the slewing braking start timing to stop the stewing structure at a slewing stop angular position in accordance with a predetermined slewing deceleration and the subsequent target slewing angular velocity, based on the remaining slewing angle of the slewing structure. When the slewing structure stops before the slewing stop angular position due to disturbance despite the foregoing control, the target slewing angular velocity is corrected to be increased for generating slewing torque to restart the slewing.
