摘　　要：以ZL40G装载机为研究对象,根据装载机工作装置电液比例控制系统的结构建立其数学模型;采用模糊自整定PID参数法设计了位置控制器,运用Matlab/SIMULINK模块进行了仿真研究;通过与普通PID算法的仿真结果进行比较,结果表明:采用模糊自整定PID参数法能消除系统负载干扰,可显著提高稳态特性,具有较好的自适应能力。Taking ZL40 G as the object of the loader,this paper builds the math models on the basis of the structure of the Electric proportional,and designs the position controller by the fuzzy self-tuning PID parameter method. By using Matlab / Simulink module,the simulation study was conducted and the results showed that the load disturbance could be eliminated by using this approach and the steady state characteristics could be improved to a better self-adaptive capacity.
