位置控制系统..docx

PAGE \* MERGEFORMAT 17 摘 要 位置随动系统是指用来控制被控对象的某种状态或某个过程，使其输出量能自动地、连续地、精确地复现或跟踪输入量的变化规律。其控制行为的主要特征表现为输出“服从”输入，输出“跟随”输入。位置随系统运用越来越广泛，大至控制上吨重的巨型雷达天线，小至用音圈电机来控制电视放像机的激光头。从国防、工业生产、交通运输到家庭生活，它的应用几乎遍及社会的各个领域。 这次设计面向开放实验室自动控制系统DIY实验，设计一个小功率单片机位置随动系统。设计内容包括确定总体控制方案、硬件选择、单片机PWM控制程序、位置检测程序、数据处理和控制程序，并进行硬件安装、软件烧入、系统测试，调试，改进和运行。 关键词：位置随动系统；PWM；程序；安装；调试  Abstract Position servo system is used to control the controlled object’s certain state or process, make its output automatically、continuously、accurately repetition or tracking input’s change rule.The main characteristics of its control behavior is shown as output obey input, output follow input. Position servo system used more and more widely. Big to control tons of large radar antenna, Small to use voice coil actuator to control the laser disc player TV. From the national defense、industrial production、transportation to the family life. Its application almost throughout all areas of society. This design cater to the Open automatic control system for DIY laboratory experiment. To design a Low power Single chip microcomputer position servo system.Design content including the overall control scheme、Hardware options、Single chip microcomputer PWM control program、Position detection program、Data processing and control program, and carry on Hardware installation、Software burn-in、The system test, debugging, to improve and run.
