Abstract:
To move an actual locus of a predetermined part of an attachment near a target locus, and to suppress necessity of measuring data for moving an actual locus near a target locus in advance.SOLUTION: An actual speed ratio calculation means 81 calculates an actual speed ratio that is a ratio of an arm cylinder actual speed to a boom cylinder actual speed. A target speed ratio calculation means 82 calculates a target speed ratio that is a ratio of an arm cylinder target speed to a boom cylinder target speed. A target speed correction means 83 corrects at least one of the arm cylinder target speed and the boom cylinder target speed to a side where the actual speed ratio moves near the target speed ratio, when the actual speed ratio is different from the target speed ratio.SELECTED DRAWING: Figure 5
