it so rare, The outputs of this Vi are Transformer's currents so must to be sinusoidal signals too, when I run th VI The problem is this:
First the Vi start to run, but the signal decrece so fast and in the end The error persists
The corrects results should be :
The Block Diagram of this circuit is based in a Simulink Diagram
is so frustrate jeje, but maybe is a configuration error, i don't know what to do.
Sorry for the inconvenience but I really need to resolve this

Hello Vendetta,
I assume that this is an example from a textbook? What are the inputs ln_v1 and ln_v2? Is there any additional information in the textbook regarding this model that perhaps we are missing?
07-14-2010 04:56 PM
well in fact The name of The the textbook is
Dynamic Simulations of Electric Machinery: Using MATLAB/SIMULINKPrentice-Hall PTR 1998, ISBN 0-13-723785-5Chee-Mun Ong |
But, there no parameters, so in INTERNET i found a Document with this implementation and, with some changes, in other document the model is similarity. In my proyect i must to make the following simulations: The Transformer lineal and No lineal case (saturation) and variable Frecuency i attach the documents, the textbook have a big size , this is the reason why i didn't attached.
In the first document (no linear) you will found a proyect in simulink. there are a diagram block is similar to what we have been working
Figure 5 i already tried this diagram and i have not worked, i hope you find it usefull. here you will find the voltages and the results should be obtained in fact, the autors used equation of the Textbook before mentioned
Thanks for your interest in helping

Hi!!
Here i found the solution in mathlab code in the offical page of the bookText, attach this, may be can help you too
The resolution is there

C4 after click en sla.m or sla.mdl
anyway i copied and pasted it into a document
Take care

Do you know the two inputs that were used for simulation?
Also each of the integrators seem to have an initial condition as well.

I am trying to modelling a tank system and I had the same error "Error - 2335" But i have checked everything and I don't get what's wrong. I am using Labview2011, I send the file, if anyone can help me I really will apprecciate it.

DMX,
What are the differential equations that describe your system? The sqrt introduces negative terms and it seems to drive h_2 to inifity.
02-06-2012 09:35 PM
The equations are attached. But I just implemented the same scheme in Simulink an it worked, because h1 is allways greater than h2. I really do not understand because I did the same model in Simulink
