That's exactly what the D term _can_ do
Funny, I just did another on-line class that covered PID.The behavior
you describe seems to be common. The class used an elevator example and

not a clue as to good values to use. I think one could use a pyvcp led
to indicate the autotune is done and ready for use.
It seems to me that it could be used to co
