Simulation Analysis and Optimization of Control Characteristics of Hydraulic Direct-Drive Door Pivot Oscillating Mechanism Based on Multi-software Platform
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 AMES-im,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 suit-able control parameters.The simulation results show that compared to ordinary PID control,the system overshoot of fuzzy PID control al-gorithm is reduced by 75.32%,the adjustment time is shortened by 29.56%,and steady-state error is reduced by 71.97%.
