To enhance the control characteristics of the hydraulic direct-drive door pivot oscillating mechanism， reduce overshoot and steady-state error and other key indicators,a multi-software integrated mechanical and hydraulic systems co-simulation method was used to analyze and optimize the system control characteristics.In order to increase the accuracy of the simulation model，the AMESim,ADAMS and MATLAB software were used to establish a co-simulation model.Considering the time-varying characteristics and dead zone of the oscillating mechanism,an adaptive fuzzy PID control algorithm was employed to improve the control system by adjusting suitable control parameters.The simulation results show that compared to ordinary PID control,the system overshoot of fuzzy PID control algorithm is reduced by 75.32%,the adjustment time is shortened by 29.56%， and steady-state error is reduced by 71.97%.
