Abstract
A method, using multiple position sensors, for determining a characteristic of the actuator or a system, wherein the characteristic is causing or is indicative of the cause of the change in position of the actuator. One characteristic may be the lost motion of the actuator or system. Lost motion is the lag between the motion of a controlled device and that of an electrical drive device due to yielding or looseness. The lost motion of an actuator may increase as components wear and may eventually degrade the function or cause failure of the actuator and/or system.
