PID is the hello world of Control Theory which can be used to solve very complex control requirements by iteratively processing feedback. For example these quad-copters juggling use CT even though you may think this is only possible with some kind of machine learning algo.

- phkahler 11y ago>> PID is the hello world of Control Theory... While that's true, it's surprisingly effective and as a result is very widely used.
- TeMPOraL 11y agoIs there something more complicated that's actually used?
- phkahler 11y ago>> Is there something more complicated that's actually used? Yes, absolutely. It's less common but so are the people who can implement them.
- TeMPOraL 11y agoThis was my indirect way of asking for examples :).
- phkahler 11y agoAnd that was my indirect way of deferring to someone farther down the path than me. But Wikipedia has a detailed overview: http://en.wikipedia.org/wiki/Control_theory http://en.wikipedia.org/wiki/Control_theory I was surprised not to see Kalman listed in the people section. His contribution: http://en.wikipedia.org/wiki/Kalman_filter http://en.wikipedia.org/wiki/Kalman_filter Turns out to be important sometimes - like when your sensors don't quite give you what you want. But when things get to that level, I call in a specialist to make sure it's done right - got one on speed dial, he does controls full time all the time.
