Abstract
A construction machine includes: a flow rate regulating part which regulates a flow rate of hydraulic oil supplied from a hydraulic pump to a hydraulic actuator, and a control device—which controls driving of a work device. The control device includes: an acquiring part for acquiring a motion state amount of a combined center of gravity of a plurality of members which constitute the work device; and a generating part which generates an instruction value for controlling an operation of the flow rate regulating part such that the motion state amount follows a predetermined first target value, the instruction value being used for executing a feedback control based on the first target value and the motion state amount, and inputs the instruction value to the flow rate regulating part.
