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.

Claim (Index 1):
A control circuit, capable of operating an actuator, comprising:\n a drive circuit connected to the actuator and comprising:\n a first output terminal; and \n a second output terminal; \n a digital signal processing circuit connected to the drive circuit and configured to:\n measure waveform characteristics of a back electromotive force (EMF) induced by the actuator; and \n compute a countermeasure value according to the back EMF; \n a signal generator circuit connected between the digital signal processing circuit and the driver circuit and configured to generate an output signal; and a selector circuit connected between the drive circuit and the digital processing circuit, wherein the selector circuit is responsive to the output signal and configured to selectively couple one of the first output terminal and the second output terminal to the digital signal processing circuit according to the output signal; wherein the drive circuit is configured to operate the actuator according to the countermeasure value.
