Proportional gain
Displays the gain value for the PID controller.
2
Integration time
Displays the integration value for the PID controller.
3
Derivation time
Displays the derivation value for the PID controller.
4
Disturbance
An additional measurement that also influences the controller;
Dist out=distance–average distance*P. gain.
5
Deadbandwidth
The area around the setpoint where control does not move.
6
P out
Difference*P gain.
7
I out
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.
8
D 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.
