Lightbulb Two variable PID? I know someone's done it =)...

My team hasn't done it, but I'm SURE someone out there has:

A PID loop that controls BOTH velocity and position. Basically it allows you to say "I want to move 33 feet forward, and do it at 6 fps."

The PID loop manages both the acceleration to the target speed, keeps track of the distance travelled, and decelerates and corrects as you approach your target distance.

Surprisingly, I did a search on CD, and didn't come up with much, although I probably missed something .

Overviews, explanations, even code snippets would be much appreciated!
