To realize a hydraulic control system capable of performing feedback control based upon a detected value related to hydraulic drive in a stable state.

This hydraulic control system includes a liquid pressure circuit for controlling the hydraulic drive of load 10 by a servo valve 20, and an electronic circuit 40 for performing the control following up a received command Vin for the servo valve 20. The electronic circuit 40 is provided with a correcting means 41 for obtaining a correction value according to a difference between the value of the command Vin and the detected value Vf related to the hydraulic drive, and providing the same for controlling the servo valve 20 according to the command Vin, and the correction value is updated intermittently at time intervals corresponding to the responsiveness of hydraulic drive.
