Abstract
This paper discussed the design and experimental verification of a new digital position control method for a high-speed optical disc drive. The position control method needs to improve disturbance suppression capability, as the disc rotation speed becomes higher. We apply a repetition compensator in order to reduce repeatable position error. The control system is implemented in an optical disc drive set-up. The optical disc can rotate at speed of 9000rpm and its sampling frequency is 176kHz. The experimental results that the proposed repetition compensator with 5th order compensator can reduce both the focus and the tracking error caused by the disc disturbances.
