An axisymmetric vector nozzle hydraulic servo system based on fuzzy PID control was designed for the functional re-quirements of the axisymmetric vector nozzle.The system was modeled and simulated jointly by AMESim and MATLAB/Simulink,and compared with the conventional PID control to analyze the response characteristics of the system and verify the feasibility of the redun-dant backup function and fault return function of the electro-hydraulic servo valve.The simulation results show that the designed axisym-metric vector nozzle hydraulic servo system has good performance,and the system with fuzzy PID control has better steady-state charac-teristics,dynamic characteristics and stronger robustness,and the redundant backup function and fault return function of electro-hydrau-lic servo valve are verified to be practical.
