| Research Abstract |
This research proposes a control system for suppressing tracking error offset and multi harmonic disturbance in high speed optical disk systems. Residual tracking error consists of primary harmonics, high-order harmonics, and offset. Therefore, this research proposes a tracking control system for suppressing residual tracking error, including primary harmonics, high order harmonics disturbance, and offset. The experimental results show that the proposed system enables an optical disk system to achieve a fine tracking performance.
