Abstract
This paper proposes a feedforward control scheme to control the bouncing instability of active-head air-bearing slider. The principle of the scheme for stability control of bouncing slider is discussed. Simulation results show that the control scheme is proved to be able to substantially reduce the bouncing vibrations. Compared to other controllers, the proposed scheme is less computationally intensive and is thus suitable for real time implementation.
