A summary of recent research in micropositioning and nanopositioning is presented. The
work is classified into five groups by actuation approach, including piezoelectric, magnetic …

Conventional thin-film processing techniques remain inadequate for obtaining superior
dense ceramic thick films. The incompatibility of ceramic films prepared via other methods …

This paper presents a settling control of a dual-actuator system for hard disk drives. The dual-
actuator system consists of a voice coil motor (VCM) as a first stage actuator and a push-pull …

Discrete time, 25 KTPI track-following servos were designed for magnetic hard disk drive
dual stage actuators using the/spl mu/-synthesis methodology. The design methodology was …

We introduce a static error analysis technique, based on smart interval methods from affine
arithmetic, to help designers translate DSP codes from full-precision floating-point to smaller …

A decoupled control design structure and discrete time pole placement design method are
proposed for MEMS-based dual-stage servo control design in magnetic disk drives. Dual …

Presents a method for the design of controllers for linear time-invariant dual-input/single-
output (DISO) systems in continuous-time or discrete-time. The new method reduces the …

Feedback control of microelectromechanical systems (MEMS) devices has the potential to
significantly improve device performance and reliability. One of the main obstacles to its …

Positioning precision is crucial to today's increasingly high-speed, high-capacity, high data
density, and miniaturized hard disk drives (HDDs). The demand for higher bandwidth servo …

This paper presents the design of a digital dual stage servo and the analysis of its robust
stability and performance. The dual stage actuator system consists of a coarse actuator and …
