Abstract
A hard disk drive with a circuit that provides a control signal to a voice coil motor to move a head across a disk of a drive. The circuit includes a state estimator that provides a plurality of state estimates and a disturbance estimator that provides a disturbance estimate that is combined with the state estimates to define the control signal. The disturbance estimator compensates for flex cable disturbances, particularly during a settle mode of a seek routine.
