I am writing a script to set parameters for a parsim() simulation. But I want to save signals at each simulation case into a specific file name, so that at the end of the run I will like to see a number of files created for each case. I have gone through the help-matlab but still is not clear for me how to solve my case. Here are specific queries that I would like somebody to clarify them. (Thanks in advance)
1.- How to save signals into a external file (*.mat) for each simulation case when running parasim()?. I have tried the following code but it doesn't work. I don't see any file creted neither in my workspace nor in my project FOLDER
in(i) = Simulink.SimulationInput('sldemo_househeat');
in(i) = in(i).setBlockParameter('sldemo_househeat/Set Point',...
'Value',num2str(SetPointValues(i)));
in(i) = in(i).setModelParameter('SimulationMode','accelerator',...
'LoggingFileName','name',...
out = parsim(in,'ShowSimulationManager','on','ShowProgress','on');
However, If I select "signal loging" from Configuration Parameter as below
I can Only see my file name inside the structure "out", but this is not what I want. I would like the script to create a file (*.MAT) in my project FOLDER for each test case
It seems some progress here, but how to do this PROGRAMMATICALLY (from script)?
Regarding naming the output file, I will need to rename the file for each case that parsim() runs, otherwise the last case will override the previous one. Here is my attempt (doesn't work) :
in(i) = Simulink.SimulationInput('sldemo_househeat');
in(i) = in(i).setBlockParameter('sldemo_househeat/Set Point',...
'Value',num2str(SetPointValues(i)));
name = strcat('case_number',i,'.mat');
in(i) = in(i).setModelParameter('SimulationMode','accelerator',...
'LoggingFileName',name,...
out = parsim(in,'ShowSimulationManager','on','ShowProgress','on');
2.- My Simulink model has already several signals selected as "log Selected Signal" (85 signal toal). But for my parsim() case I want to save ONLY a partial number of signals (15 signals). How to do this? is there a programmatically way to do it?, Do I need to un-log all signals and log only the ones I need?
3.- I have a signal created in a script ("TotalFAConnectedSB"), I move this signal into my Simulink model, log it (selecting ""log Selected Signal") so it can be saved it along the other logged signals, BUT it triggers an error when run parsim(). What Can I do in this case, how can i save a signal that is constant all the time. And also I would like to save a PARAMETERS within the log output so I can Plot it. is this possible?
*.m file code:
TotalFAConnectedSB = C1+C2+C3
where C1,C2,C3 are input parametsr (defined in the same script) to a simulink block.
