Vibration sensor feedforward control for magnetic storage device
Abstract:
A magnetic storage device that includes a housing, including a base, a cover, and an interior cavity. The magnetic storage device also includes an actuator controller, located in the interior cavity and configured to generate an actuator command signal. The magnetic storage device further includes an actuatable component, located in the interior cavity, and an actuator, located in the interior cavity and operable to actuate the actuatable component in response to the actuator command signal. The magnetic storage device also includes a vibration sensor, located in the interior cavity and configured to detect a vibration of the cover. The magnetic storage device further includes a sensor feedforward controller, located in the interior cavity and configured to generate a gain signal, based on the vibration of the cover detected by the vibration sensor, and to modify the actuator command signal proportional to the gain signal.
