This paper presents a study on active control of the flow-induced vibrations (FIVs) on head gimbals assemblies (HGA) inside hard disk drives (HDDs), including analogue demonstrations and digital close-loop implementations. The results show that the feedback pressure fluctuations generated by a piezo...
