How do I get a feedback controller for active suspension system in simmechanics?

Hi, I simulated a quarter car with pasive suspension in simmechincs and didn't have any problem with it, however I can't transform it to an active suspension. I tried the same approach as here Control Tutorials for MATLAB and Simulink - Suspension: Simulink Simscape (umich.edu) but that doesn't work. Can anyone help me with this problem that I have? Is another completly different method needed? Here is the file of my simulation . Thanks!

Hi Sajmir. The approach shown in Control Tutorials for MATLAB and Simulink - Suspension: Simulink Simscape (umich.edu) is correct, but you need to supply a force input to a joint. This is what it should look like.

See if you can follow the tutorial using this as your force input.
