摘　　要：为提高凸轮轮廓加工精度,减少廓形误差,引入了模糊自适应PID迭代学习控制方法。基于X-C轴联动误差模型,通过分别对X、C轴进行模糊自适应PID迭代学习控制减少单轴的跟踪误差,从而减少凸轮廓形误差。基于MATLAB建立X、C轴模糊自适应PID迭代学习控制仿真模型并在不同磨削速度下进行仿真实验。结果表明:与常规控制方法相比,模糊自适应PID迭代学习控制能够在一定程度上提高凸轮的加工精度,并有效较小廓形误差。To improve the machining accuracy of the cam,and reduce the contour error,the fuzzy adaptive PID iterative learning control was proposed here. Based on the X-C axis linkage error model,and taking the advantages of fuzzy adaptive PID learning control to reduce the tracking error of X and C axis,thus the cam contour was reduced. Based on MATLAB,building the simulation model of fuzzy adaptive PID learning control on X and C axis,and testing the model. The simulation results showed that the fuzzy adaptive PID iterative learning control could reduce the contour error to some extent.
