毕业设计（论文） 论文题目 基于单片机的伺服 电机控制器 摘 要 随着电力电子技术、智能控制技术的发展成熟，伺服机控制器已成为自动化装置的一个重要部分。例如，印刷机应用了伺服机控制器来控制电机的转速和传送长度。本论文阐述了基于单片机的伺服机控制器的控制原理，位置控制和电子齿轮的特点和应用，采用单片微机 AT89S52 作为中央控制器， AM26LS31 为驱动器。AT89S52 主要与Σ－Ⅱ控制器连接了位置控制，方向控制,正反转限制等。AT89S52 从 P1 口输出脉冲序列，利用Σ－Ⅱ控制器电子齿轮简便设置，控制伺服电机的总转动角度，控制输出脉冲的频率就可以控制伺服电机的速度，以达到控制伺服电机的目的。此外还介绍了Σ－Ⅱ的控制器的结构连接图，特性，功能和用户常数设定， SGM □ H 型伺服机的发展,优点和工作原理。还有介绍伺服系统的基本内容。 关键词：伺服系统；位置控制；电子齿轮；单片机AT89S52 ABSTRACT As development of electric and electronic technology , intellectual control technology being ripe, the servo machine controller has already become an important part of the automatic device . For example, the printing machine has used the servo machine controller to control the rotational speed of the electrical machinery and length of conveyance. This thesis has explained the principle of control based on servo machine controller of the one-chip computer, position control and electronic characteristic and application of gear wheel, adopt single blocks of computer AT89S52 as the central controller, AM26LS31 is a driver . AT89S52 has connected position control with controller mainly, directional control, rotate positive and negativly and limit etc.. AT89S52 outputs the pulse array from P1 mouth, utilizes controllers electronic gear wheel to be set up simply and conveniently, controlling always rotating the angle of the servo electrical machinery, controlling the frequency of outputting the pulse can control the tempo of the servo electrical machinery , in order to achieve the goal of controlling the servo electrical machinery. In addition has recommended the structure of the controller of connect and pursue , the characteristic, the function and users constant are established , SGM .The development of the type servo machine , the advantage and operation principle. Still introduce the basic content of the servo system. KEY WORDS: Servo system ；Position control； Electronic gear wheel ； One-chip computer AT89S52 引 言 中国数控技术和产业经过40多年的发展，从无到有，从引进消化到
