Abstract :
This paper proposes a time optimal control method for track-to-track seek. Deadbeat control is applied to model following seek control, in which a single control architecture covers seeking and tracking control. Time delay between head position detection and VCM input was compensated. Experimenting with this control method upon a 2.5 inch HDD, we confirmed that it showed the good performance and control robustness
