Abstract
In this paper, reduction of flow induced suspension vibrations in a hard disk drive by dual-stage suspension control has been investigated. The design of the servo controller uses both a dynamical model of the suspension and a model for the stochastic dynamic behaviour of the wintage design a 3/sup rd/ order discrete time controller that reduces non-repeatable run-out errors.
