An Adaptive Model Based Disk File Head Positioning Servo System.
Abstract
The feasibility of controlling a disk file head positioning servo with an adaptive computer simulation model is investigated. During the seek mode, model updating of position, velocity, and motor gain parameter are accomplished from samples of head position only, thereby eliminating the requirement for a tachometer in the positioning servo system. In the track follow mode, three methods of linear compensation are presented to settle the transients of the servo and allow for the positioning of the read/write head on track center in minimum time. Implementation of the simulation model into a microprocessor is also investigated. Keywords: Theses; Digital data storage; Computer programs. (Author)
