    Ted talk / origin of the PID

    Just came across this randomly on YouTube Tedx talk by one the inventors of the PID in coffee machines.

    Hopefully a few find it interesting.

    FYI He's not one of the inventors of the PID. He may have invented A PID, but he did not invent THE PID.

    Fair enuff electronic snobs :-) What I should have said, one of the first people to use a PID in a commercial coffee machine.

    Here is an interesting article about earliest use of PIDs in coffee machines;

    Funny you should say that as the first true PID was used to steer a ship in the 1920's.

    Newton or Leibniz did the groundwork.

    Even older than that, I think. The device to which you refer is presumably Elmer Sperry's "Metal Mike", introduced in 1922, but Sperry had also developed the first autopilot for aircraft use ten years earlier.

    Nah, Sperry's work on his controller was intuitive. I was referring to the work of Nicolas Minorsky who in 1922 for the first time developed a formal control law for PID(s) using theoretical analysis. This allowed him to build a device which controlled the angular velocity of the rudder rather than the angle of the rudder. A subtle but telling difference that for many gives him the nod for having made the first true PID.
