In view of the existing hydraulic servo control systems- advantages and disadvantages, a new composite hydraulic servo control system with dual independent closed-loop based on servo motor, definite displacement pump, accumulator and servo valves was put forward with the trend of high performance and energy-saving. Its structural characteristics were analyzed, and the mathematical model was made. The simulation analysis and experiments have shown that it can fulfill the performance of each control component and achieve the flow adaptation. Comparing with the existing control scheme, the new control system is simple, reliable and has made great improvement in comprehensive indicators, and is fit for airborne hydraulic system and missile hydraulic system.
