Meanwhile, the article on gyroscopic autopilot (both maritime and aeronautical) makes no mention of PID controllers, despite that being the field in which the theory of PID controllers was developed.
PID controllers are all around us. They make elevators accelerate and decelerate without knocking passengers to the floor or pinning them to the ceiling, they stabilize video for pros and consumers alike, they make anti-lock brakes work, and nearly every other automated task in the software and physical world where the control needs to be adjusted based on observed conditions.Wikipedia quotes: mathematical models of vagueness and ignorancehttps://maisonbisson.com/post/wikipedia-quotes-mathematical-models-of-vagueness-and-ignorance/Sun, 11 Nov 2018 16:06:55 -0800https://maisonbisson.com/post/wikipedia-quotes-mathematical-models-of-vagueness-and-ignorance/[F]uzzy logic uses degrees of truth as a mathematical model of vagueness, while probability is a mathematical model of ignorance.
