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...
متن کاملExperimental Evaluation of Triple - Stage - Actuator System with Thermal Actuator for Hard Disk Drives *
Abstract To improve positioning accuracy in a head-positioning control system for hard disk drives, we have developed a triple-stage-actuator system on a spin-stand tester. In this system, the first stage is a VCM actuator for moving a head-stack assembly, the second stage is a PZT actuator for moving a suspension, and the third stage is a thermal actuator for moving read/write elements. The fr...
متن کاملMechatronics of Electrostatic Microactuators for Computer Disk Drive Dual-Stage Servo Systems
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-stage track following controllers are designed using a decoupled three-step design process: the voice coil motor (VCM) loop design, the microactuator (MA) inner loop design, and the MA outer loop design. Both MIMO (when the...
متن کاملH2 Guaranteed Cost Control Design and Implementation for Dual-stage Hard Disk Drive Track-following Servos
This paper discusses the design and implementation of H2 guaranteed cost control for dual-stage hard disk drive trackfollowing servo systems. The proposed approach is based on H2 guaranteed cost analysis, in which an upper bound on the worst-case H2 performance of a discrete-time system with gainbounded unstructured uncertainty is determined via several Riccati equations. Subsequently, the outp...
متن کاملDesign, Fabrication and Control of Micro-Actuators for Dual-Stage Servo Systems in Magnetic Disk Files
Since the first hard disk drive (HDD) was invented in the 1950s by IBM, disk drives’ storage density has been following Moore’s law, doubling roughly every 18 months. The current storage density is 10 million times larger than that of the first HDD (Yamaguchi, 2001). Historically, increases in storage density have been achieved by almost equal increases in track density, the number of tracks en...
