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

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 ?

Try "To workspace" block: https://www.mathworks.com/help/releases/R2020a/simulink/slref/toworkspace.html

I used the same block to workspace.

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 !!
