DEVELOPMENT OF OPTIMIZED ADAPTIVE FEED-FORWARD CANCELLATION WITH DAMPING FUNCTION FOR HEAD POSITIONING SYSTEM IN HARD DISK DRIVES

Development of Optimized Adaptive Feed-Forward Cancellation with Damping Function for Head Positioning System in Hard Disk Drives

This paper presents an adaptive feed-forward cancellation (AFC) technique with a damping function based on optimized AFC.The proposed AFC includes a mechanical resonance characteristic as an internal model that is realized by using the damping function and that Diapers achieves the best performance in the frequency domain.This makes it possible to
