Hard Disk Drives


Funding: Seagate

Robust Control of Dual-Stage Drives: A typical hard disk drive (HDD) works by spinning a magnetic disk while the magnetic head reads/writes data from/to circular tracks on the disk. Modern hard drives utilize a dual stage actuator system consisting of a voice coil motor and a micro actuator. The robust control framework is used to design a single controller that provides stability and performance for all drives within a single product line. The objective of this research is two-fold. First, computational tools are being created to automate the construction of uncertainty models from frequency response data. Second, design and analysis tools are being developed to account for temperature variations.
