Abstract
This paper describes the application of fuzzy logic control on the track-seeking motion in the head-positioning servomechanism of a hard disk. There are two major operations in the head-positioning servo of a hard disk, i.e. seeking and tracking. The seeking controller performs minimum-time movement of the read-write heads from their current track position to a target track specified by the file controller. The dynamic behaviors of the head-positioning servo is highly nonlinear, which make the derivations of an analytic model very difficult. A fuzzy seeking controller is designed and implemented on a high precision hard disk driver, the Zentek ZM3140. The proposed seeking controller can successfully move the read-write head servo mechanism to the desired target track. Our experimental results also show fast responses and robust behaviors of the servo system.
