matlab simulink simstate issue
显示 更早的评论
hi everyone,
I am trying to use Simstate to stop, save and reload my model in order to save my data a couple of times before the whole simulation is actually done.
I've tried using :
set_param('mysim','SaveFinalState','on','FinalStateName','myOperPoint','SaveCompleteFinalSimState','on');
sim('mysim','StopTime','10');
set_param('mysim','LoadInitialState','on','InitialState','myOperPoint');
sim('mysim','StopTime','20');
but it seems that the model save "myOperPoint" isn't getting saved if the model does not reach it's actual end.
Does anyone have a clue how to actually use this because the official tutorial isn't helping me much.

I notice the same thing. If I use this, then SimState is not saved:
set_param('mysim','SaveFinalState','on','FinalStateName','myOperPoint','SaveCompleteFinalSimState','on');
sim('mysim','StopTime','10');
but if I do this, then the SimState is saved:
set_param('mysim','SaveFinalState','on','FinalStateName','myOperPoint','SaveCompleteFinalSimState','on');
sim('mysim');
.

I just tried the following, and it ran to the desired stop time and saved the SimState:
set_param('mysim','SaveFinalState','on','FinalStateName','myOperPoint','SaveCompleteFinalSimState','on');
set_param('mysim','StopTime','10');
sim('mysim');

Whenever I build a Simulink model, I like to set the stop time to a parameter which is defined in the Matlab workspace, e.g.
set_param('mysim','StopTime','sim_StopTime');
So, when I run the model, I define the sim_StopTime parameter in a script, and then run the model. Using this method, the following worked for me:
set_param('mysim','SaveFinalState','on','FinalStateName','myOperPoint','SaveCompleteFinalSimState','on');
sim_StopTime = 10.0;
sim('mysim'); % SimState successfully saved
set_param('mysim','LoadInitialState','on','InitialState','myOperPoint');
sim_StopTime = 20.0;
sim('mysim'); % Sucessfully loaded the saved SimState and ran out to 20 seconds
