Abstract
Systems and methods are disclosed for calibrating actuators in a multi-stage servo system. In certain embodiments, a method may comprise performing a calibration process on a multi-stage actuated servo system, including: seeking the multi-stage actuated servo system to a selected location, via a first stage actuator; providing a first voltage injection to a first microactuator of the multi-stage actuated servo system; measuring a first position error signal (PES) of the multi-stage actuated servo system; determining a first gain for the first microactuator based on the first PES, without adding a signal injection to the first PES; and applying the first gain to the first microactuator.
