众文网1.labview能否读取数据库中的数据?比如Acesse或者Excel等
可以的！
在Acesse中读取数据，建议用LABSQL，比较易学，可以满足对数据库的基本操作。
LABSQL可以理解成一些子VI，通过调用这些子VI（譬如打开数据库，执行对数据库操作，关闭数据库操作什么的）对数据库进行控制，这里面控制的语言用得是SQL语言，如果不对数据库进行复杂操作，还算很容易上手的（给你推荐个网站，是讲这个SQL语法的，.cn/sql/sql_insert.asp）
LABSQL是LABVIEW与SQL连接的一种方法而已。你可以网上容易的找这些LABSQL的子VI。我也可以传给你。
读取EXCEL，可以用，函数—文件I/O—读取电子表格文件VI，不过要注意的是，这种方法读取的EXCEL文件是用LabVIEW的“写电子表格文件”生成的。如果是简单EXCEL表格，可以把内容复制到txt文档里，再读取。
以上是我所知道的两种比较简便的方法，如有更好的方法，欢迎交流
2.用labview做毕业设计,遇到问题,急问
可以通过matlab 节点写入传递函数，给你一段matlab建立传递函数的代码吧，希望有用
（我做的是PID+CMAC复合控制）
clear all;
close all;
ts=0.001； %采样时间
sys=tf(1770,[1,60,1770])； %传递函数参数
dsys=c2d(sys,ts,'z');
[num,den]=tfdata(dsys,'v')； %传递函数的分子和分母从线性模型
y_1=0;y_2=0;y_3=0； %输出初始化
u_1=0.0;u_2=0.0;u_3=0.0； %输入初始化
x=[0,0,0]';
%PID参数设定
kp=25;
ki=0.0;
kd=0.28;
%PID控制输出
up(k)=kp*x(1)+kd*x(2)+ki*x(3);
%仿真输出
yout(k)=-den(2)*y_1-den(3)*y_2+num(2)*u_1+num(3)*u_2;

找到labview有关的外文文献 要原文我有Development of a Distant Laboratory using LabVIEW*K. K. TAN, T. H. LEE and F. M. LEUDepartment of Electrical Engineering, National University of Singapore, 10, Kent Ridge Crescent,Singapore 119260. E-mail: kktan@nus.edu.sgThis paper presents the development of a distant laboratory experiment for engineering students atthe National University of Singapore. The experiment is concerned with real-time modeling andcontrol of a pilot-scale DC servo motor. The World-Wide-Web (WWW), with its ability to delivermultimedia and graphics across the world, is used as the medium to link the student to a remoteexperimental setup located in the distant laboratory. This paper describes the hardware andsoftware constructs which facilitate students to perform the experiment remotely and efficiently,using only a commonly available, user-friendly web browser.------------------------------------------------------------------------------- INTRODUCTIONMASS PRODUCTION of books has made educationavailable to many, and provided the fundamentalresources for the system of mass educationtoday. At the dawn of the information technology(IT) age, available infrastructure and technologiesare well poised to bring education to even more byallowing individuals to carry more responsibilityfor their own learning and achieve independence ofthought and action by means of distant education.In the present era, distant education is becomingimportant and necessary for several reasons. Withthe advent in IT, the exponential rate in theaccumulation of information and rapid changesin information and technology necessitates anongoing education and professional development.Distant education, with the tremendous potentialin terms of time and space flexibility, has much tooffer in this respect. This is particularly true forthe engineering profession where rapid advancementin technology and innovation necessitatesmore efficient and flexible means of accumulatinglatest know-how and updated information. This isalso probably a reason for the changing studentdemographics as life-long continuous learning hasbecome the sole means necessary for engineers toremain relevant and competitive. A large percentageof university students, especially thosepursuing higher degrees, are enrolled on a parttimebasis with full family and work commitments.Convenience and flexibility in the curriculum in acontinuing education system is thus of utmostimportance.Distant education has been through severalstages since its inception in the mid to late 1800s[1]. Development of inexpensive and faster postalservices in Europe and across the United Statesgave birth then to the correspondence or homestudy form of education. Readings, study guidesand other print materials are sent to students bymail. Students gain credit by completing specificassignments. This is the first generation of distanteducation. In the late 1960s and early 1970s, thesecond generation of distant education surfacedthrough the use of recorded media such as radios,televisions, audiotapes and telephones. These newways of communication complement the studyguides and local library resources available.Distant education, in its present generation, isturning towards the powerful integration ofcomputers and telecommunications to bring onreal time interaction. The Internet is the world'slargest, most powerful computer network connectingpersonal computers, sophisticated mainframes,and supercomputers around the globe. TheWorld-Wide-Web (WWW), as the fastest growingInternet service, is seen as an effective tool fordistant learning. The WWW project, started byTim Berners-Lee while at CERN (the EuropeanLaboratory for Particle Physics) [2], seeks to builda `distributed hypermedia system'. The WWWprovides Internet users with a uniform and convenientmeans of accessing the wide variety ofresources (pictures, text, data, sound, video)available on the Internet. Popular softwareinterfaces, such as Internet Explorer (IE) andNetscape, facilitate navigation and use of thework* Accepted 9 September 1999. infrastructure cripples the usefulness ofWWWas a。
