However the development of the technology of embedded micro control and field bus have resolved this prolem , so that the process control of modern train has developed from concentrated direct digital control system to distributed control system basing on network 但是计算机技术和现场总线技术的高速发展很好的解决了这个问题,它将现代列车通信的过程控制从集中型的直接数字控制系统发展成为基于网络的分布式控制系统。
A srm direct digital control system based on dsp controller is designed . the hardware and software based on single neural cell self - adaptive pid control algorithm is designed . consideration of data exchange between the dsp and can , communication software and interface circuit between dsp and can bus is designed 在分析开关磁阻电机调速系统( srd )和dsp特点的基础上,本文进行了采用单神经元自适应pid为控制算法、基于dsp的srd设计和dsp与can总线之间数据通信的软硬件设计。
In this paper , it is carried out the controlled system of single - chip microcomputer ( at89c52 ) , which is based on ddc ( direct digital control ) , to resolve the synchronization of the amount of seeding transplant and velocity , and utilize series voltage regulator to resolve the stability of the voltage 本文采用型号为at89c52单片机(单片微型计算机single - chipmicrocomputer )的直接数字控制( directdigitalcontrol )技术,解决摆秧机行走速度与摆秧量同步性的问题。
Based on direct digital control technology , this paper puts forward a new type of synthetic platform for dc motor control . its goal lies in fully utilizing the resources in labs and making users understand the basic concepts and principles about dc motor control and automatic control tec hnology with less investment and simple devices 本文基于直接数字控制技术,提出了一种新型的直流电机控制综合平台,目的在于充分利用现有的实验室计算机资源,以较少的投资和简单的实验设备让使用者了解直流电机控制和自动控制技术中的一些基本概念和基本原理。
As the first to provide direct digital control technology for building automation , the first to embed a web server in a building controller and the first to provide complete integrated solutions based on open systems for building it , a company of profound service culture and professional knowledge , with the help of its parent company , schneider electric s source advantages , tac has acquired quick development in chinese market and participated the prestigious projects , such as national theater , national high court , guangzhou exhibition centre , beijing friendship hospital , tsinghua university sports centre and so on C .凭借母公司施耐德的优势资源已经在中国市场获得了长足的发展,先后承揽了包括国家大剧院、最高人民法院、广州会展中心、北京友谊医院及清华大学体育中心在内的一系列国家重点工程。而施耐德电气在实现对tac及安德沃的收购、重组后将更加从容面对2008年北京奥运会及2010年上海世博会带来的机遇和挑战。
