ABSTRACT:
A system and method of providing floating actuator control is provided. This system and method receives input command signals from an actuator controller, and effectively integrates these signals until the controller has requested a large enough movement of the actuator that the actuator can actually effectuate. At this point, the system and method drive the actuator to the commanded position. As a result, excessive mechanical wear in the actuator caused by small command signal perturbations and dither is reduced or eliminated.
