摘要：
The present invention includes: a displacement altering unit for generating a displacement control pressure corresponding to a displacement control signal; an input unit for inputting a target displacement; a pressure calculating unit for calculating a displacement control pressure corresponding to the target displacement based upon predetermined reference characteristics of the displacement altering unit; a pressure detecting unit for detecting a pressure corresponding to the displacement control pressure; a signal calculating unit for calculating a displacement control signal corresponding to the input target displacement; and a correcting unit for correcting the displacement control signal calculated by the signal calculating unit based upon the displacement control pressure having been calculated by the pressure calculating unit and the measured pressure detected by the pressure detecting unit.
