I and II order instruments [ITA-ENG]

Сообщение Zaen »

Salve a tutti.
Io sono italiano, spero che quacluno mi capisca e mi aiuti a risolvere il problema che ho.
Vorrei creare con Labview due strumenti, uno capace di simulare il comportamento del PRIMO ORDINE e uno del SECONDO ORDINE.
Purtroppo ho tentato, ma senza grossi successi. La mia idea era quella si creare un generattore di segnali come input, mentre come output
vorre sia un grafico della risposta in funzione del tempo che sia un valore numerico. Vorrei pure settare manualmente i vari paramentri per
vedere come cmabia la risposta dello struemento.
Vorrei allegare il VI che ho già creato, ma non so come fare: consigli?

Se ho sbagliato sezione, mi scuso in anticipo.
Aspettando risposte un saluto a tutti

Hello everyone.
I am Italian, I hope someone understand and help me solve my problem.
I would like to create two instruments, one capable of simulating the behavior of a First-order and one of second order.
Unfortunately I tried, but without much success. My idea was to create a signal generator as input, while output
is a graph of response versus time or a numeric value. I would also manually set the various parameters for
see how the response changes.
I would upload the VI that I have already created, but I do not know what to do: advice?

If I'm wrong section, I apologize in advance.
Waiting for answers greetings to all

Hi!

Thank you for writing in both - italian and english. You can append your VI or make a screenshot of your block diagramm.

As I understand you want to make a simulation of a filter of first and second order. Lowpass? Did you see the following example for doing that?

Thank you very much for your answer (and your speed!).
Excuse me if i write now, but i had not internet for this holiday.
I use labview from 2 weeks, so my knowledge about this is little.

Your VI is very good, but i don't understand some steps..but i hopo to improve this studying!!
I want to make a differt VI; in my idea there is this block diagram:

When i write particular input i think step, ramp (increasing and decreasinf), impulse and sine input (i don't know if the translation from italian is correct)
In this image thera are the differential equation of I and II order, and the responses (outputs) of I order instrument with theese inputs:

I have tried to make this instrument, but i have not hadsucces. This is my VI:

How can I obtain a continuos graph? (i have a point moving when time value t changes)
I hope I was clear..

Thanks for your support!

Ciao Zaen,
non puoi semplicemente caricare il tuo vi? Facendo così si può utilizzare il tuo vi e modificarlo per aiutarti, altrimenti uno deve ricostruire il vi da zero .....(tempo ).
