<p>Disclosed is a control device for a work machine on a construction vehicle such that a bucket cylinder is stopped at a target position, with high accuracy achieved in a bucket cylinder length, and with shock held down to a low level. A bucket cylinder length detection section (101) references a cylinder length detection table (102) on the basis of a boom angle and a bell crank angle, thereby detecting a bucket cylinder length. A bucket attitude control section (103) controls the bucket cylinder length so that a target position will be reached. Feedback control is performed until a set value which is set short of a target value is reached. After the bucket cylinder length reaches the set value, open loop control is performed until the target value is reached.</p> |
