摘　　要：为提高液压直驱门轴摆动机构的控制特性,减小超调量以及稳态误差等关键指标,基于多软件机液一体化联合仿真方法对系统控制特性进行仿真优化。为了提高仿真模型的精度,使用AMESim、ADAMS以及MATLAB软件建立联合仿真模型;针对摆动机构存在的时变性、死区等问题,采用自适应模糊PID控制算法调整合适的控制参数,对控制系统进行改进。仿真结果表明:相比普通PID控制,调整后的模糊PID控制算法系统超调量减小了75.32%,调节时间缩短了29.56%,稳定误差减小了71.97%。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%.
