I am trying to build a controller for a unycicle, but when I try to send the configuration to the workspace for doing the polts, I have that the values of x,y and theta are all zeros. Moreover, the values of the input velocities are just two, and I don't get what is happening.
I attach my model.
Can somebody please help me? I have been on this problem for long time.
Thanks in advance

Hi Flavio
just a fews minor bugs
1/ your x and y are not initilaised , by default your integrator blocks IC are set by default to zero
so x and y IC = 0 , so next value for v = 0 so idem for x_dot and y_dot , and so on, everything remains at zero the entire simulation
to fix that I change the IC values (see the initialization file and the simulink blocks changed are in green color)
2/ minor bug also on the indexes for v and omega data - this is why you had not the entire data vector.
I send you back the files and hope you can continue your work
