摘　　要：针对电液伺服开度控制系统存在的非线性、负载扰动、时变性等问题,以蝶阀的阀门电液伺服开度控制系统为研究对象,使用AMESim软件搭建该系统的物理模型,使用MATLAB软件搭建控制模型,将二者进行联合仿真,并对常规PID控制(proportional-integral-derivative control)和自整定模糊PID控制两种算法的控制性能进行对比。实验结果表明:与常规PID控制相比,采用自整定模糊PID控制方式的电液伺服开度控制系统超调量更小,调节时间更短,准确性有很大提升,且对扰动也有很好的鲁棒性。In view of the problems existing in the electro-hydraulic servo opening control system,such as nonlinearity,load disturbance and time variability,in our present study the electro-hydraulic servo opening control system of butterfly valve was taken as the research subject,AMESim software was used to build the physical model of the system,MATLAB software was used to build the control model,and the two were jointly simulated.Furthermore,the control performance of conventional proportional-integral-derivative control(PID control)and self-tuning fuzzy PID control was compared.The experimental results show that compared with the conventional PID control,the electro-hydraulic servo opening control system with self-tuning fuzzy PID control mode had smaller overshoot,shorter adjustment time,greatly improved accuracy,and also had good robustness to disturbance.
