An Object Oriented Framework for the Synthesis of Robust Multi-rate Controllers for Hard Disk Drives (HDD)

摘要

This paper proposes an object oriented framework to model and synthesize robust multi-rate controllers for many of the track-following servo configurations encountered in the hard disk drive (HDD) industry, including traditional single-stage and new dual-stage servos. The proposed object oriented software will be used to synthesize and evaluate the tracking performance of different single-stage and dual-stage servo designs, given realistic Track-Mis-Registration (TMR) budgets.
