摘 要
在控制系统中，若给定的输入信号是预先未知且随时间变化的，并且系统的输出量随输入量的变化而变化，这种系统就称为随动系统。快速跟踪和准确定位是随动系统的两个重要技术指标。传统的伺服控制系统通常采用模拟随动系统，即用运算放大器及外围电阻、电容元件实现比例、微分、积分校正网络，来改善系统的动态及静态特性。实际工作中我们感到模拟伺服随动系统具有算法呆板，电路调试繁琐，系统响应慢等诸多不足。随着计算机技术、现代控制理论的迅猛发展，由数字控制装置组成的随动系统即数字随动系统应运而生。
数字随动系统 是输出量以一定精度复现输入量变化的自动控制系统, 它在对生产过程和运动对象的控制中, 以及在定位、瞄准、跟踪等装置中都占有显著的地位, 现己成为各种自动调节系统的组成部分。
本文的研究对象是数字随动系统,并结合数字随动系统的原理设计一个比较简单的数字随动系统实验装置。

Abstract
In the control system, if the input signal is given in advance of the unknown and change over time, and change due to the change in output with the input, this kind of system is called a servo systemIs fast tracking and accurate positioning servo system of two important technical indicatorsServo control systems are often used for traditional analog servo system, using operational amplifiers and peripheral resistance, capacitance components to achieve scale, differential, integral calibration network, to improve the system of dynamic and static characteristicsIn the actual work we are simulating algorithm of servo system with rigid, circuit debugging cumbersome and inadequate systems respond slowly and many otherWith the rapid development of computer technology, modern control theory, by numeric control servo system of the digital servo system came into being
