Work Machine

A work machine comprising:

• a machine body;
• a work device attached to the machine body;
• an actuator that drives the machine body or the work device;
• a hydraulic pump;
• a directional control valve that controls a flow of a hydraulic fluid supplied from the hydraulic pump to the actuator;
• an operation lever that gives an instruction for operation of the actuator;
• and
• a controller that controls the directional control valve according to an input amount of the operation lever,
• wherein a pressure sensor that senses an actuator pressure as a pressure of the actuator is provided, and
• the controller is configured to
• calculate an actuator target pressure as a target pressure of the actuator on a basis of the input amount of the operation lever,
• calculate, as a pump first target flow rate, a target flow rate of the hydraulic pump for reducing a difference between the actuator target pressure and the actuator pressure,
• calculate, as a pump second target flow rate, a target flow rate of the hydraulic pump for reducing a difference between an actuator absorption flow rate as a flow rate absorbed by the actuator with driving of the actuator and a pump flow rate as a flow rate supplied from the hydraulic pump to the actuator,
• calculate a pump final target flow rate as a final target flow rate of the hydraulic pump on a basis of the pump first target flow rate and the pump second target flow rate, and
• control the hydraulic pump according to the pump final target flow rate.
