摘要
A data storage device is disclosed comprising a disk, a head, and a microactuator configured to actuate the head over the disk. An input signal to a compensator is generated, wherein the compensator is configured to generate a microactuator control signal. A slew rate signal representing a slew rate of the microactuator control signal is generated and applied to a first saturator configured to generate a saturated slew rate signal. The input signal is adjusted based on the slew rate saturation signal, and the microactuator is controlled based on the microactuator control signal.
