co838_ab981 0:c0509139a295 27 *
co838_ab981 0:c0509139a295 28 * A PID controller is a widely used feedback controller commonly found in
co838_ab981 0:c0509139a295 29 * industry.
co838_ab981 0:c0509139a295 30 *
co838_ab981 0:c0509139a295 31 * This library is a port of Brett Beauregard's Arduino PID library:
co838_ab981 0:c0509139a295 32 *
co838_ab981 0:c0509139a295 33 * http://www.arduino.cc/playground/Code/PIDLibrary
co838_ab981 0:c0509139a295 34 *
co838_ab981 0:c0509139a295 35 * The wikipedia article on PID controllers is a good place to start on
co838_ab981 0:c0509139a295 36 * understanding how they work:
co838_ab981 0:c0509139a295 37 *
co838_ab981 0:c0509139a295 38 * http://en.wikipedia.org/wiki/PID_controller
co838_ab981 0:c0509139a295 39 *
co838_ab981 0:c0509139a295 40 * For a clear and elegant explanation of how to implement and tune a
co838_ab981 0:c0509139a295 41 * controller, the controlguru website by Douglas J. Cooper (who also happened
co838_ab981 0:c0509139a295 42 * to be Brett's controls professor) is an excellent reference:
