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 ...

Multirate adaptive notch filter with an adaptive bandwidth controller for disk drives
(2008)This paper presents the simulation results performed of a multirate adaptive notch filter with adaptive bandwidth controller for disk drives. The resonant modes of a disk drive may be uncertain and vary between units, and ...

Position error signal estimation at high sampling rates using data and servo sector measurements
(2003)The sampling rate in most hard disk drives (HDDs) is limited by the number of servo burst sectors that have prewritten position error signal (PES) data and by the spinning speed of the HDD. This paper presents an algorithm ...
