Hi @ayoub reffai
Didn't notice this previously. Anyhow, can you post the equivalent mathematical model that describes the linearized dynamics of what is shown in your Simscape model? For example,
If you have the original control-affine nonlinear model, then also can.
If you don't know the model, you can probably try using this linearize() command. See Example here:
https://www.mathworks.com/help/slcontrol/ug/linearizing-nonlinear-models.html
But I notice a something labelled "PI" here. If that is related to your PID, then the "D" must be missing. Would you point out where your D is?
