Since the manipulator was born, the various difficult problems were easily solved. In this design the present condition of research about domestic and international manipulator and development trend of research concerning PLC were introduced. The principle of work and the process of action’s realization of manipulator control system were described. The design of manipulator model control system based on PLC was researched and MCGS’s application in the manipulator model control system was researched. The interface of supervision for the manipulator model control system was designed by MCGS. An intuitive, clear and accurate manipulator operating state was provided. And then various possibilities for maintain and breakdown’s diagnosis were provided, the work’s efficiency of system was fully elevated. Key words: manipulator; PLC; MCGS 目 录 摘 要 Ⅰ Abstract Ⅱ 第一章 绪 论 1 1.1 课题研究目的及意义 1 1.2 国内外机械手研究概况 1 1.3 课题研究的内容 2 第二章 机械手控制方式的选择和可编程序控制器简介 3 2.1 机械手控制方式的选择 3 2.1.1 控制方式的分类 3 2.1.2 PLC与工业控制计算机（IPC）和集散控制系统（DCS）的比较 3 2.1.3 机械手控制方式的选定 4 2.2 可编程序控制器简介 5 2.2.1 PLC的结构…………………………………………………………………
