High track density has been achieved by adopting an H, controller with a feed-forward compensator using adaptive filter theory in a sector servo system. In applying the H,,, control theory, a state-space model of an augmented plant was constructed considering the input location of the disturbance. M
As the track density of hard disk drives increases, further improvement in the performance of the read/write head positioning servo system is required. However, the servo performance is limited mainly by the inherent mechanical resonances of the head actuator. Passive damping has the potential to im
This study aims to develop a sliding mode based learning controller for track-following in hard disk drives. The proposed controller incorporates characteristics of sliding mode control into learning control. The reason for using sliding mode control is attributed to its robust properties dealing wi
