چکیده

This chapter demonstrates the use of anti-windup compensation in the control loop of a micro-actuator which is nominally controlled by a linear, discrete robust controller. The micro-actuator is part of a hard disk drive dual-stage servo-control system for positioning of the read/write head. The actuator inputs are constrained to retain the micro-actuator’s displacement range of less than 0.4 μm for mechanical protection.

Robust Control of an Electrostatic Microelectromechanical Actuator

A continuing trend these days is the use of micro-electro-mechanical actuators with electronic circuitry to fabricate MEMS devices such as micro-switches, hard disks, optical micro-mirrors ... One of the problems with the electrostatic MEMS actuator is that when an electrical voltage is applied to these devices, the micro-actuators undergo a residual vibration before reaching their permanent po...

Modeling product variations in hard disk drive micro-actuator suspensions

The increase in aerial storage capacities of future magnetic hard disk drives has fostered the use of dual-stage actuators for high track density data recording. In a hard disk drive with a dual-stage actuator the standard rotary actuation of the voice coil motor is combined with an additional micro or milli actuation to accomplish high-bandwidth and highly accurate track following. In order to...

Modeling and Control of a Dual Stage Actuator Hard Disk Drive

A data-based approach is presented for modeling and controller design of a dual-stage servo actuator in a hard disk drive. The servo actuator in this hard disk drive consists of a conventional voice coil motor and a piezo-electrically actuated suspension. A weighted Hankel matrix based realization algorithm that uses frequency domain data is applied to estimate a discrete-time model of the voic...

Design Optimization of Actuators Using ANSYS

Research and development on actuators has been accelerated with the aid of virtual prototyping software, like ANSYS. This is illustrated with two successful cases using ANSYS to design and optimize micro-electromechanical actuators. The first case is topology optimization of head suspension assembly for hard disk drive. The second case is design optimization of polymeric thermal micro-actuator....

Suppression of cross-track vibrations using a self-sensing micro-actuator in hard disk drives

In this study we utilize the self-sensing capabilities of piezoelectric micro-actuators in hard disk drives (HDD) to actively suppress in-plane resonance modes of the suspension in an HDD. The self-sensing circuit is based on a tunable capacitance bridge that decouples the control signal from the sensing signal in the micro-actuator. A hybrid modeling technique based on a realization algorithm ...
