The purpose of this application note is to describe how a PIC16F684 can be used to implement a positional Proportional-Integral-Derivative (PID) feedback control in an inherently unstable system. An ...

Pid now offers an Easy Mode in addition to its existing Normal and Hard difficulties, and many of the adjustments were made based on community feedback, developer Might and Delight announced today.

The introduction of inverse feedback and control loops incorporating it was a brilliant advance in the history of engineering, but it was soon followed (probably on that very same day!) by the ...
