https://en.wikipedia.org/wiki/PID_controller
"A proportional-integral-derivative controller (PID controller) is a 
generic control loop feedback mechanism (controller) widely used in 
industrial control systems. "

There are three tuning constants, and they are now usually tuned with 
various algorithms instead of entirely by hand. Following Ian's 
suggestion shows that Python is one of the languages used for such 
algorithms.

Renato should have searched first as a search now is a bit contaminated 
by multiple hits for the post here and on mirrors ;-).
