摘　　要：提出双动液压实验机上、下位机联合控制的总体控制方案。下位机以TMS320LF2407A为核心控制器,详述其硬件部分的设计。并介绍上、下位机软件的功能,阐述数字PID控制算法和系统数据传输协议的实现。操作者根据工艺要求分别对压边油缸和冲压油缸的速度和位移进行预先设置,可获得液压缸的实际速度曲线。The overall control scheme of host-computer and slave-computer combination control of double-action hydraumatic tes- ting machine was put forward. TMS320LF2407A was the core controller of slave-computer, and its hardware design was expanded. The functions of host-computer and slave-computer software were introduced, and the realizations of digital PID control algorithm and system data transmission protocol were represented. Based on technological requirements, operator can respectively preset the veloci- ties and displacements of two hydro-cylinders and can obtain the actual velocity curves of hydro-cylinder.
