Abstract
In accordance with an embodiment, an actuator control circuit includes a driver circuit connected to a ringing characteristic determination circuit. A signal generator that is configured to generate an output signal having first period that has first and second portions where the first portion longer than the second portion is connected to the ringing characteristic determination circuit. Another embodiment includes a method for controlling an actuator by determining a resonant frequency and a ringing amplitude of an actuator signal; generating a control signal in response to the resonant frequency and the ringing amplitude of the actuator signal; and causing the actuator to move in response to the second drive signal.
