Abstract�� Taking the constant power control of the airborne pump supplying as the goal, and addressing on the load variation during the process of the operation, the control strategy for keeping the output power constant to increase the utilization degree to the power of the engine was used. For the main controlled plant of the airborne pump supplying system with the variable displacement axial piston pump, the state space equation and flow output equation were built and the H�� robust control strategy was used to regulate the flow of variable displacement pump. The simulation results show that the system could quickly return to a new flow state corresponding to constant power working curve when the load was changed. The H�� controller can decrease the affections from the disturbance and uncertain parameters for the system stability and can be of a strong robustness. It could improve working performance and utilization degree of the system.
