Long-span seek control system for hard disk drive without mode-switching

In hard disk drives (HDD) there are two control modes: the head positioning control mode and the other is the seek control mode. In the head positioning control mode, a feedback controller is optimally designed to suppress disturbances. In the long‐span seek mode, a velocity feedback control system...
