Abstract
A system and method for monitoring freeplay within an actuator is provided. In accordance with various embodiments, the method includes collecting a plurality of actuator parameter data sets during a predetermined period. During the predetermined time period the actuator drive motor is commanded to extend and retract an actuator output ram operably connected to a movable component of a structural system such as a mobile platform. The method additionally includes selectively isolating various sets of the plurality of actuator parameter data sets that meet specific predetermined criterion. Furthermore, the method includes computing an amount of freeplay value within the actuator based on the isolated actuator parameter data sets.
