Abstract

This paper proposes a new robust servo system for optical disk recording system with feedforward controller based on prediction of error. In optical recording systems, the feedback servo system must suppress the influence of the force disturbance and parameter variation. For this purpose, this paper designs the robust feedback control system by using the coprime factorization and disturbance observer. The detecting signal of optical disk recording system is only a error. Hence, the feedforward controller of the proposed control system is constructed based on both zero phase error tracking (ZPET) control theory and prediction of error. The experimental results point out that the proposed system has a quick and precise response and keeps the residual error below tolerance.
