摘要
随着现代信息技术的发展,以提高产品加工的生产效率为主的高度自动化和以提高产品的质量为主的精密化成为现代机械加工技术发展的两个主要方向。人们对航空机、数控机床、精密仪器和仪表以及各种精密机械设备提出了越来越高的精度要求,X-Y作台是这些设备实现高精密加工的核心部件,对于提高产品的加工质量起着尤为重要作用。
通过对几种运动控制方案的比较,决定采用ATMEL公司的 AT89s51单片机作为主控制芯片的运动控制方案。它是AT89c51单片机的升级版,不仅支持更高的极限工作频率,具有ISP(在线更新程序)功能以及拥有对c51单片机的全面兼容性,并且还具备了c51单片机的结构简单、价格低廉、开发周期短等优点。本设计分为硬件和软件两个部分。硬件部分设计主要包括芯片的选型、伺服系统的选型、单片机模块的设计、电源系统的设计、输入/显示界面的设计等。系统硬件设计采用模块化的设计方法,使系统具有良好的扩展性和经济性。软件部分包括通过编写输入/显示子程序,通讯子程序,插补子程序等控制所必须的子程序函数库,最终实现了使交流伺服电机轴按设定的曲线运动的功能等。

Abstract
With the development of modern information techniques, the high automation with the main purpose of improving the production efficiency of product process and the accuracy with the accuracy with the main aim of improving the quality of product have been ing the two major directions of the modern technique of mechanical process. People on the air machines, CNC machine tools, precision instruments and meters and all kinds of sophisticated machinery and equipment raised higher and higher precision, XY for Taiwan is that these high-precision machining equipment to achieve the ponents, for improving the quality of processed products play Is particularly important role.
Through parison of several motion control program, the dissertation introduced to use the pliant single-chip AT89s51 made from pany America as the main control program of the motion control. It is more advanced than the single-chip 80c51 and has a simple structure, low cost, the advantages of short development cycle. The system is divided into two parts, hardware and software. The main part of the design of hardware includes: chip selection, servo motion selection, single-chip modules design, power
