The hard disk drive is one of the finest examples of the precision control of mechatronics,
with tolerances less than one micrometer achieved while operating at high speed …

An adaptive robust controller (ARC) has been recently developed for read/write head
embedded control systems of hard disk drives (HDDs). This structure is applicable to both …

Currently, HDD (Hard Disk Drive) with VCM actuator covers more than 80% of the HDD
market. To enhance the capacity and ability of the system, a new class of servo controller is …

A hybrid optimization method for the production of work order group furnaces was proposed
in this paper. First, a working order group furnace model was constructed including …

The spectra of disturbances and noises affecting precise servo positioning for ultrahigh-
density storage in future hard disk drives are time-varying and remain unknown. In this …

High aerial density is needed for improving the capacity in Hard Disk Drive (HDD). In order
to achieve this task, tracking performance and robustness of HDD servo system need to be …

In this paper, a new adaptive robust approach for non-minimum phase systems is proposed,
based on the synthesis algorithm of dynamical backstepping design procedure. The …

In this paper, adaptive robust controllers are proposed for dual-stage hard disk drives. An
improved desired compensation ARC (IDCARC) scheme is proposed in this paper for both …

The position of the magnetic head of a hard disk drive used in a computer is a critical
variable. This chapter considers the design of a hard disk drive system to achieve control of …

In this paper, an OICA (Online Iterative Control Algorithm) by setting measured PES
