  • In this paper, a digital feedback control closed-loop is presented for active suppression of flow-induced vibrations on a head gimbals assembly (HGA) in a working hard disk drive (HDD). In this closed loop, a laser Doppler vibrometer was used to detect the flow-induced HGA off-plate vibration as feedback error signals, a digital controller was implemented to filter the feedback signals, and a piezoelectric disk stuck on the HDD cover inner surface was employed to actuate feedback acoustic… CONTINUE READING
