Abstract: In this paper, a phase lead peak filter (PLPF) design method is adopted to adaptively compensate for high frequency contact-induced vibration (CIV) in hard disk drive (HDD) servo systems. Based on the prior investigation of CIV, a baseline feedback controller is first employed to stabilize the servo loop, and then add-on peak filters are connected in parallel with the baseline controller to further suppress the vibrations in the high frequency range. The proposed CIV compensation scheme has a simple control structure, is capable of dealing with multiple vibration modes that may not be within the bandwidth of open-loop transfer function, and is robust to the change of CIV in frequency and magnitude. The performance of the proposed method in CIV compensation is validated by simulation and experiment. © 2013 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society.
