OK... I'm getting old, and I've been put to sleep in surgery a BUNCH of times. I've forgotten a LOT of stuff. But I'm having troubles understanding exactly what a PID controller is and how it works. Are they commercially available?
Can someone help me out with this?
Please and thank you for your trouble.
