How to extract data from simulink to work space in matlab?

19 views (last 30 days)
I tried to design a LQR controller. I wrote the code and design a simulink model.
I wanted to extract data from simulink to workspace.
But when i run the code it says error in time which i have written as t= sim_X.time.
How can I solve the issue?
I have attached the screen shot below.

make sure it is sim_X.time or sim_X.Time or sim_X.tout. Visualize it in workspace

so, this is my simulink model
since, i realise, there is out.sim_X in workspace, i changed myy code to
t= out.sim_X.time which was previously written as t=sim_X.time
i still get the same error.
"Unable to resolve the name out.sim_X.Time.
Error in codeviayoutube (line 84)
t=out.sim_X.Time; "
what is wrong? is there any other command ?

But still i get the same error when i changed to t= out.sim_X.time

Have you selected "Timeseries" as save format inside the To workspace block?

Try this:
simOut =sim('simulinkviayoutube')
t = simOut.sim_X.time;
x1 = simOut.sim_X.signals.values(:,1);
x2 = simOut.sim_X.signals.values(:,2);
it will help you !!
