Abstract: Aiming at the problems of the increase in orifice loss caused by high pressure and large power of the airborne hydraulic power system, a kind of intelligent power supply system which sets operation mode and reference input according to the assignment of the airplane was proposed. The control and management of the intelligent pump is really a hierarchical computer control system. The upper computer is responsible for the determination of operation mode and reference input. The lower computer, i.e., micro-controller, is responsible for the realization of the control law, the transformation of digit to analogue, and data acquisition. For the convenience of integration, a scheme of micro-controller was presented, it integrated the lower computer, signal condition circuit and servo amplifier, and the micro-controller was developed. The smart hydraulic power supply can select the operating mode and the input of controller according to the flight assignment, and realize the effective management of the power utilization, so that the rising of temperature is effectively restrained and the maneuverability and the existence ability are increased.
