Adaptive disturbance rejection for disk drives using neural networks
(2008)This paper presents the experimental verification of an adaptive feedforward disturbance rejection scheme for hard disk drives. The control scheme is shown to reduce the error during track-following by as much as 11.8%. ...

Adaptive mode-suppression and disturbance-rejection scheme with application to disk drives
(2009)The goal of a track-following controller for a disk drive is to maintain as close to perfect tracking as possible. Better tracking allows for more data to be stored on a single disk. There are several factors which make ...

Identification and high bandwidth control of hard disk drive servo systems based on sampled data measurements
(2007)One of the key factors that determines the track density of a hard disk drive (HDD) is the performance characteristics of the HDD servo system, the control system that positions the READ/WRITE magnetic head close to the ...

A neural-networks-based adaptive disturbance rejection method and its application to the control of hard disk drives
(2009)This paper presents a neural-networks-based disturbance rejection adaptive scheme for dealing with repeatable and nonrepeatable runout simultaneously. The effectiveness of this method is demonstrated empirically on a ...

Position error signal estimation at high sampling rates using data and servo sector measurements
(2002)Track density in hard disk drives (HDD) is related to the performance characteristics of the HDD servo control system. Higher track density can be achieved by improving the performance characteristics of the servo controller ...

Servo Control Design for a Hard Disk Drive Based on Estimated Head Position at High Sampling Rates
(2003)In this paper we use the ACORN estimator that generates estimates of the head position by processing servo burst and data sector measurements of the mean square error (MSE), to provide head position error measurements at ...
