Abstract
An intelligent optical disk drive control method for rapidly and accurately controlling the movement of an optical pick-up head of an optical disk drive, including the steps of: (a) defining a movement mode for the optical pick-up head; (b) providing a reference message according to the movement mode defined by step (a); (c) moving the optical pick-up head according to the reference message provided by step (b), and providing a feedback message subject to the actual movement of the optical pick-up head when the optical pick-up head is moved; and (d) comparing the feedback message with the reference message, then using a fuzzy control and a proportional integration control to adjust the movement mode of the optical pick-up head subject to the comparison result, so as to let the actual movement mode of the optical pick-up head follow the predetermined movement mode.
