Abstract

See full text

A pump control device and a valve control device each includes: an instruction calculator that calculates a control instruction of causing a controlled object to operate by using a manipulation amount of a manipulation and at least one control parameter, and inputs the calculated control instruction to the controlled object; and an ideal output calculator that calculates an ideal output of an actuator, the ideal output being associated with the manipulation amount of the manipulation. The pump control device adjusts at least one pump control parameter to reduce a difference between a control output and the ideal output when an operation of a movable part is a power running operation. The valve control device adjusts at least one valve control parameter to reduce a difference between a control output and the ideal output when the operation of the movable part is a non-power running operation.
