I Like This Concept of PID

I like this concept of PID because it makes its decisions based on the current and last scan.

PID Means What?

At first, I really tried to understand what "PID" means, and after net browsing, I found out it stands for proportional-integral-derivative (PID) controller, which is a generic, control-loop, feedback mechanism (controller). Wow. What a term! Sorry, but I'm not really a technician or a mechanic, and I had to search it for real.

I Was Not Aware

I was not aware of some of these advantages and disadvantages of the PID controller. This is of great help to me as I am a research student.
