چکیده
In this paper, and mixed / controllers are designed for a hard disk drive (HDD) using linear matrix inequalities (LMIs). In the proposed algorithm, the problem of minimizing track misregistration (TMR) in the presence of unmodeled dynamics of voice-coil motor (VCM) is formulated as robust and mixed / problems. Additional stack variables are introduced to characterize and performances. The simulation and comparison results demonstrate the significant performance improvement of TMR under unmodeled dynamics of VCM. Keywords—Linear matrix inequalities(LMIs), hard disk drive, robust control

Nonlinear Pid Control of Linear Plants for Improved Disturbance Rejection
A nonlinear PID (NPID) controller for a class of linear plants with output feedback is studied. The controller gains are modulated by the control error and error rate to yield a closed-loop system for improved disturbance rejection. An optimization problem involving constraints written as linear matrix inequalities (LMIs) is solved to compute the controller parameters. A hard disk drive (HDD) c...
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 کاملHard disk drive seeking profile optimisation via linear programming
In this article we develop an approach to design track-seeking controller for hard disk drive. We convert the current multi-sine seek approach to an equivalent linear programming problem that can be solved efficiently and accurately. We demonstrate the efficacy of this approach by numerical case studies that are otherwise infeasible in the current approach. We further derive the time optimal tr...

The paper established the remote access to hard drives via browser with Xilinx's XUPV5...
متن کاملFretting Wear between a Hollow Sphere and Flat Surface
Wear particles in a hard disk drive may cause the head/disk interface to fail. We have experimentally investigated wear particle generation resulting from fretting wear between the dimple on the suspension and the gimbal spring. We have found that increasing the normal load as well as using a low friction coating reduces the formation of wear particles. INTRODUCTION Examination of failed hard d...
