Abstract
A combination of setting a correction value of an atmospheric temperature for each temporal section in response to a predicted value of a variation of the atmospheric temperature in a day and a delayed variation of a temperature of hydraulic oil due to thermal inertia and correcting a command value for a temperature regulation of the hydraulic oil at a supply source of the hydraulic oil in response to the correction value of the atmospheric temperature, performing a feed forward compensation of the temperature of the hydraulic oil with respect to the variation of the atmospheric temperature for the day as a cyclic period, permits a working body of hydraulic oil to be kept at an adequate temperature, even under working conditions subjected to significant influences of atmospheric temperature variations and thermal inertia.
