To enhance the control characteristics of the hydraulic direct-drive door pivot oscillating mechanism and reduce key performance indicators such as overshoot and steady-state error, a multi-software electromechanical integrated simulation based on AMESim, ADAMS, and Simulink was used to investigate and optimize the system control characteristics. With the aim of improving the accuracy of the simulation model, the three-software integrated simulation model was built to simulate the system control characteristics. By addressing system variability, dead zone nonlinearity, and pressure fluctuation, an adaptive fuzzy PID control algorithm was applied for optimization of system control. Based on a comparative analysis of multiple experimental sets, the control system adjusted the appropriate control parameters. Ultimately, the simulation results revealed that the modified fuzzy PID control algorithm reduced the system overshoot by 75.32%, shortened the settling time by 29.56%, and decreased the steady-state error by 71.97% compared to the conventional PID control.
