Modeling and Control of a Dual Stage Actuator Hard Disk Drive

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010
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.
