Item
Displays the gain value for the PID controller.
Displays the integration value for the PID controller.
Displays the derivation value for the PID controller.
An additional measurement that also influences the controller;
Dist out=distance–average distance*P. gain.
The area around the setpoint where control does not move.
Difference*P gain.
I out + (difference*P. gain)/I Time.
Example: I out at the start = 0, difference = constant. After 1*I. time,
I out will be equal to P out. After 2*I. time, I out will be 2*P out.
Change in the difference within D. time*P. gain.
Example: if D. time is 10 s, the past difference (from 10 s ago) is 1
and the current difference is 3, D out will be (3–1)*P. gain.
