1. A mobile hydraulic generator comprising:

  • a flow generator including n pumps operated by n motors to generate an amount of a hydraulic fluid;

    a proportional hydraulic control valve to control output hydraulic pressure according to the amount of the hydraulic fluid;

    a pressure sensor to detect the output hydraulic pressure; and

    a hydraulic servo loop controller to generate a pressure control signal for controlling the proportional hydraulic control valve based on a required hydraulic pressure and a change amount of the output hydraulic pressure and to generate an RPM input signal for controlling RPM of the n motors, respectively,wherein the required hydraulic pressure and a required amount of fluid are input by a user, and the output hydraulic pressure is feedbacked to the hydraulic servo loop controller.
