Digital Feedback Control of the Flow-Induced Vibrations on the Head Gimbals Assembly in Hard Disk Drives: Design and Implementation

Digital Feedback Control of the Flow-Induced Vibrations on the Head Gimbals Assembly in Hard Disk Drives: Design and Implementation

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 fee...
