摘 　　 要
 大中型水闸是水利枢纽工程中的重要建筑物，保证两端油缸中的活塞杆同步运动，进而保证闸门的平稳启闭，是保证水闸安全运行的重要条件。本次论文的目的在于设计一个配水闸门双液压油缸控制系统，实现闸门开启的精确控制。
 此次设计从背景和用途出发，再逐步深入分析其内在结构原理，对比传统控制方法的缺陷基础上，深刻认识该控制系统的技术要求，通过文献研究法、功能分析法、模拟法、经验总结法等方法设计出一套可行的控制方案。
 技术路线：利用PLC控制控制变频器实现油缸电机的转速控制，并利用闸门开度传感器进行信息反馈至PLC，形成一个闭环控制系统，实现阀门两端的位移量精确控制。同时利用触摸屏建立人机交互界面，达到简易操作的目的。该控制系统包含的主要功能有：变频器跟踪纠偏，故障报警，设置开度复零，历史记录，手动纠偏。
 内容包括：控制系统所需元器件资料收集和选择，控制系统电气图和程序流程图的绘制，，控制系统程序的编写和调试等。

DUAL HYDRAULIC CYLINDERS WITH WATER GATE CONTROL SYSTEM DESIGN
Abstract
 Medium and large sluice is an important building of water control project，ensure both ends of the cylinder synchronous movement of the piston rod, And thus ensure the smooth opening and closing the sluice, that is an important condition for safe operation of sluice. This thesis aims to design a system, which controls dual hydraulic cylinders with water gate and achieves to control the sluice’s opening accurately.
     The design goes from the background and function, and then analyzes its principles of internal structure deeply. From the compare with the traditional control method, we can deeply realize the technical requirements of this control system. By documentary research, functional analysis, simulation, experience summarization can we design a valuable control plan.
 Technical line: Take advantage of PLC to control the inverter so that we can achieve to control the speed of the cylinder motor. Take advantage of gate opening sensor to feed the information back to PLC, so that it turns out to be a closed loop control system, and achieves to control the valves at both ends of the displacement. At the same time , we take advantage of touch screen to create a HMI, so that it can be much easily to operate. The main functions of control system includes: inverter track correction, fault alarm, set up zero-set opening, history, manual correction.
 The content includes: collection and selection of information about components required in the control system, the drawing of electrical diagram and flow chart about the control system, the writing and debugging of programs in the control system.
