labview circuit

[saca]

Hello Labview users,

I got a problem. I could not but a kind of wanted to make an application in Labview. Could you please help me?

Annexed to the problem I wrote a word.
I can do is attached to. "Vi" is file.

Do not post your question as a Microsoft Word document. Believe it or not, there are lots of people who do not use Word.

For those who do not have Word, here is the gist of the question:

---

Hello, I have a very big problem. I have tried to do application which I add a picture as you seen below. I have failed many times.. Could you make a favor for me? Could you design this application for me by using LabVIEW?

As you seen, there is a circuit top of the picture. Components of this circuit are resistors, capacitor, voltage regulator  and load. I need to build this circuit using LabVIEW. I have to build four graphs for this circuit. L

First graph is the output voltage of resistance.

Second graph is the output current of resistance.

Third graph is the voltage on the capacitor.

Fourth graph is the voltage of the voltage regulator.

On the right of the picture there are four controls which are related with graphs. When we decrease or increase value on the controls, we can see the differences on the graphs.

---

(I have omitted the graphs, because I believe that you do not need to read past the first sentence.)

To which my answer is: how much are you willing to pay? Perhaps a better place for you to post this is in the LabVIEW Job Openings forum, as it appears you are looking for contract work.

First of all, LabVIEW is a general programming language and environment, and not a circuit simulator such as e.g. NI multisim.

As such, you first need to collect all required formulas to simulate your circuit in pure software, then use the rich set of LabVIEW functions to implement them. How familiar are you with LabVIEW? What is the purpose of this exercise, Is this homework or part of a course? What have you tried so far and where did you get stuck? Who posed this problem?

I am graduate student. A small part of this problem, my project, I had to make labview it.

Since this is school work we will not do your work. That's why you're in school. Even graduate school. As a grad student I would expect you to be able to have the resources to solve this problem on your own, rather than coming to a public forum asking others to do your work for you. Did you plan to do that for the rest of your career as well?

Your LabVIEW program (not circuit) shows you haven't actually done anything. There's a couple of case structures and that's about it. (Note: You should never connect a case structure to a floating point value. http://en.wikipedia.org/wiki/Floating_point#Accuracy_problems)

What is your plan for getting this done? Do you have a model? You cannot do anything until you have a model. This is irrespective of whatever programming language you decide to use.

Is there a particular reason why you are trying to do this in LabVIEW as opposed to MultiSim, or is that the purpose of the assignment?

My goal is to promote the university's Labview. I have a program and want to work on Labview. I felt bad you so that you typed. Thank you.

[altenbach]

This seems like an exciting project and it can be done fully in LabVIEW. First you probably should get a solid background in general LabVIEW programming. Start here, then do some simpler projects. Get familiar with the programming environment.

While we won't do the work for you, we will be happy to guide you if you have any specific problems along the way.

Is there no one in this group can help me?

[johnsold]

You have had offers of reasonable assistance which clearly defined the expectations of those who would assist.  They expect you to do most of the work and they will help you when you get stuck.

To promote LabVIEW within the university can be a big job.  I tried for 20 years as a staff memeber and made little progress.

As both Knights pointed out you can certainly simulate a circuit like the one you have shown in LV but you need to find or create the mathematical model for the circuit first.  Then look at implementing that model in the program.

When you have a model and an attempt to implement that model in LV, then post again to show your progress.  If you have specific questions about the implementation, ask them at that time.  Include what you have tried (specific values), what did not work, and what you expect the results to be for the specific inputs.  While some of us are electrical engineers, many of those who might be helping you may not be, so you should not assume that everyone will understand all the nuanaces of your circuits.

Hi, I'm sending the application, to successfully implement Multismde did. But my work would need to Labview. For this application, I'd done Multismden Labview'e was transferred successfully and properly installed on the computer that is running Labview and Multisim. I have this application in the form of Labview exe 'converted to. Exe'si also working properly. Then Labview exe application is not installed on a computer to try and Multsim Labview'e The Run Time Engine (RTE) Labview Labview application is not installed on the computer which I installed and properly working section. But the episode does not work on Multsim. Multisim, such as the Run Time Engine with Labview arattım he could not. How can we fix this problem? Thanks.
