Hi,

My question is how I can take out (to Matlab) values from simulink simulations at specific time step?

In my example I have simple spring model. The scheme is below:

After I run the simulation with specific parameters, I get the following result.

How can I get value of position y=0.2 at time step = 80 from simulink to matlab?

Basically, I need to get final simulation results, after system equilibrates.

Thank you

在 MATLAB Online 中打开

In your scope, click on parameter icone, then History, then check save data to workspace, and set the variable name to data for example and the format to structure with time. Lunch simulation, in windows command type

t=data.time
y= data.signals.values
plot(t,y)

Check out the Sinks-Library. There are Display-, To Workspace- and To File Blocks.

In addtion there is the out block and you can set the scope accordingly.
