ABSTRACT:
Aspects of the present invention are directed to systems, methods, and computer-readable media for measuring certain actuator system parameters of an actuator, e.g., an EMA in its working environment. Stiction and backlash are examples of such parameters, and these indicate the impending failure of an actuator system than conventional approaches of measuring the elapsed time of operation. When the measured backlash and/or stiction parameters exhibit a deleterious increase over time, e.g., by exceeding a preset threshold, imminent failure or the need for service/repair of the system is indicated.
