I created a Ball on Plate system using Simskape Multibody.
It was imported as a CAD model. Now I want to control the position of the ball on the plate. For this I want to use a PID controller. I have already built the control loop. Since I don't have a mathematical model of the system I want to use the autotune function of the PID controller. But this fails.
I have tried this in two ways:
The autotune function of the PID block gives me the following error message:
Here I read in another article (https://de.mathworks.com/matlabcentral/answers/135228-pid-tune-plant-cannot-be-linearized-why) that the linearization of the controlled system can also take place at another position than the zero point. But also this approach failed.
My second approach was to parameterize the PID controller using this guide:
Again, no useful parameters come out.
Now I wonder if I have a basic problem with the PID controller blocks or Simulink or Simscape Multibody. Am I doing something wrong?
