摘　　要：以中厚板液压滚切剪为研究对象,重点解决对两路电液伺服系统的相对位移协同的控制。阐述了液压滚切剪及其机械运动过程;介绍了控制系统HMI和S7-400(PLC)的选型,给出了图形化的液压滚切剪电液伺服协同控制系统;根据交叉耦合控制理论,采用基于模糊PID的双闭环控制结构实现两路电液伺服协同控制,将MATLAB环境下仿真得到的3个PID参数的查询表导入数据块;投产后上位HMI,执行AGC系统位移数据的采集、存储和计算等功能,并监控整个生产过程,该系统可提高生产效率和产品质量。Taking hydraulic slitting shear plate as the object ,this paper focused on two way relative displacement coordination control of electro-hydraulic servo system .Firstly ,the hydraulic slitting shear and its mechanical movement process were elabora-ted;Secondly ,the control system and the selection of HMI and S7-400 （PLC） were introduced ,and a graphical electro-hydraulic servo coordinated control system of hydraulic slitting shear was presented ;According to the cross coupling control theory ,the double closed-loop control structure based on fuzzy PID was adopted to realize the coordinated control of two way electro-hydraulic servo with three PID parameters on Matlab environment simulation into the lookup table ;Using HMI ,the AGC system was con-ducted to collect ,store and calculate the displacement datum and monitor the whole production process ,which improves the pro-duction efficiency and product quality .
