This is a very very common control scheme in the embedded world. I'm surprised this is so new to so many.

  There are a lot of things that aren't part of the usual computer science curriculum, control theory being one of them. Many topics would be interesting to have some minimal exposure to, such as signal processing, operations research, etc.

  I wrote that article in 2000, and the really scary thing for me is that I'm now seeing code that obviously either came right out of it, or is only a few copy-pasta steps away from it that's just taken as "the way things are done". For the record -- it's one way to do it, but the code in there was primarily written to be as easy to understand as possible, not to be the World's Best Controller Implementation.

    Oh wow, so the article was written in 2000 and not 2016? And that's funny/scary. Hopefully those cases still end up being an improvement over not using PID at all?

  Even disciplines which typically do cover process control in undergrad often treat process control with a bit of a "there be dragons" mentality. Not for nothing are PhDs mentioned in the title; if some industry employs process control engineers, their group certainly has a concentration of PhDs well above average.
