Abstract

A control profile is generated which suppresses all the resonant dynamics in a hard disk drive flexible arm. This control profile has both the drive voltage and velocity constraints which are required in hard disk drive long seek control. The control profile is generated from the sloped fast acceleration command and the vibration suppression shape filter technology. The simulation results for hard disk drive long seek control illustrate the effectiveness of the proposed method.
