<p>PURPOSE:To provide a hydraulic system in which the actuations of desired pressure and speed can be performed even when the temperature of fluid changes. CONSTITUTION:The same actuations as at the time of setting of actuating conditions can be performed even when the temperature of fluid changes from the temperature of fluid at the time of setting of the actuating conditions, by storing the temperature of fluid at the time of setting of the actuating conditions, for instance, at the time of setting of the forming conditions such as the pressure and speed in a forming machine as a reference temperature in a reference temperature storage part 21, by preliminarily storing the characteristic data such as viscosity change for the temperature of fluid in a characteristic data storage part 22 and adding a correction to the control output from an output part 20 based on the temperature difference between the temperature of fluid detected by a temperature sensor 17 and the reference temperature and the characteristic data.</p> |
