Paper Abstract

In this paper, the objective of servo system in an optical disc player is discussed. The traditional servo method, zero- order indifferent PID adjustment, is analyzed. Based on the analysis, a new servo system, 1-order indifferent PI&PID adjustment, is provided. In the new adjustment method, the main error of low frequency from ECC and Imbalance will be reduced to minimum in theory. In the end of the paper, the stability of the new servo system is analyzed in detail.
