摘　　要：设计了一套基于PLC的电液位置伺服控制系统,主要包括液压回路设计与搭建、控制系统设计与构建、控制程序设计与调试、数据采集与分析。通过实验验证和比较系统在不同采样周期下的动态性能,并通过实验分析得出可以保证该系统动态稳定的采样周期的范围。The purposes of this article is to design the electro-hydraulic position servo control system which was based on PLC. It mainly includes designing and building hydraulic circuit, the control system design and construction, de- signing and testing control procedures, data acquisition and analysis. Specific study：.Through the experimental valida- tion and comparison of the dynamic performance in different sampling periods to put forward a range of sampling period to guarantee the system dynamic stability.
