説明
The head positioning accuracy of the hard disk drive should be improved to meet today's increasing performance demands. Vibration suppression of the arm in the hard disk drive is very useful to enhance the servo bandwidth of the head positioning system. In this study, the smart structure is introduced into the hard disk drive to suppress the vibration. First, the proof-mass actuator and the tabular PZT actuator are designed, and then the experimental set-up of the smart head actuator is developed by installing the actuators for vibration control on the objective head actuator. Second, the state-space modeling of the system is conducted by system identification approach in the experimental modal analysis for control system design. Next, the vibration controller is obtained by conducting the H∞ control problem. Finally, the closed-loop performance is evaluated by simulation and experiment.
