Abstract
Various embodiments of the present technology may comprise a method and apparatus for actuator control. The methods and apparatus may comprise various digital signal processing functions to detect a back EMF (electromotive force) and compute a countermeasure value to reduce ringing. The methods and apparatus for actuator control may apply a drive signal corresponding to the countermeasure value. The magnitude and direction of the drive signal provided at particular times during operation may facilitate a shorter settling time.
