Re: [Scilab-users] [question] xcos yielding different result than SIMULINK

[Stéphane Mottelet]

In Xcos the results are virtually the same with a plain PID block (with 
the same parameters). The chosen solver (CVODE/BDF) is OK to me.

The video is 26mn long, with several versions of the diagram. Which 
version are you addressing?
Wrt to the version at 19:00, why do you skip the 1/s block and adds an 
INTEGRAL_m block in your sent version ?

Setting the scope with ymin=0, ymax=1.5 and refresh period = 5 (or 10 or 
20) already helps showing and comparing.

OK, you have switched the positions of your integral and proportional 
branches.
Are INTEGRAL_m and INTEGRAL_f blocks equivalent? INTEGRAL_f has less 
parameters.

[Scilab-users] [question] xcos yielding different result than SIMULINK

[Foad Sojoodi Farimani]

I had initially asked the question here

on xcos Discord channel .
Basically, I want to replicate this SIMULINK tutorial
 in xcos, and so far you may see the
.zcox file in the attachment. However, my plots in xcos are quite different
from the ones in the above YouTube video. I suspect it has to do with the
default simulations parameters:

I would appreciate it if you could help me know how I can adjust the above
parameters or change the solver to get similar results as SIMULINK. Thanks
for your support in advance.

Best,
F.
