【摘要】 随着材料学研究的发展,需要一种在对材料进行微观检测时进行同步微操作的工具。本文设计了一套基于PC104的嵌入式微拉伸台控制系统,介绍了该系统的硬件组成以及软件编程。采用专用PID控制芯片实现电机的闭环控制,使拉伸台稳定地进行匀速运动。为了实现系统控制的高精度,对数据采集、原位保持等关键技术进行了算法优化。小型化、模块化、低功耗、操作简单等特点,使得本系统只需进行简单地扩展就可广泛应用于数控领域。更多还原

【Abstract】 With the development of material science,a tool is necessary to operate the material synchronously when it is being observed.This article gives the design of a micro tensile module control system which is based on PC104 embedded system.It introduces the composition of hardware and software program.The developed system used dedicated controller for PID close loop control to make the motion at a constant speed.To realize the high precision control,it added optimized algorithm to the key technologies such as data collection and original position holding.This system has the features of miniaturization,modularization,low power cost and simplification,and is easy to be expanded to digital control field.更多还原
