Working machine with hydraulics
The present invention includes a battery controller that calculates an electrical storage remaining amount of a battery, a charging/discharging request calculation part that calculates a charging/discharging request amount for keeping electric power outputted by the battery within a predetermined range based on the electrical storage remaining amount calculated, a target rotational speed calculation part that calculates a target rotational speed command value of a motor generator, and an inverter that controls the motor generator according to the target rotational speed command value calculated, and it is configured that at least one of the battery controller and the inverter calculates the actual charging/discharging amount of the battery, and that the target rotational speed calculation part calculates a target rotational speed correction value from difference between the charging/discharging request amount and the actual charging/discharging amount and corrects the target rotational speed command value.
