... section. Basically, the majority of commercially available HDD servo systems to
date are designed using a conventional PID approach. For drives with a single VCM
actuator, designers would encounter ... These draw-
backs can be overcome by using our newly developed control techniques.
We design an HDD servo system that meets the following design constraints and
specifications:
1. the contro...

... switching. More-
over, the RPT controllers in a track-following servo have been proved to be robust
against resonance mode changes from disk to disk and work well against runout
disturbances.
The MSC ... The most
popular nonlinear control technique used in the design of HDD servo systems is the
so-called proximate time-optimal servomechanism (PTOS) proposed by Workman
[30], which achi...

For actual drives, prewritten PES data might be estimated at high sampling rates
using servo sector measurements (see, for example, [141]). In disk drive applications,
the variation ... Track-
following servo systems have to ensure that the PES is kept to a minimum. Having
deviations that are above the tolerance of the disk drive would result in too many read...
