Abstract
The subject matter of this specification can be embodied in, among other things, a method for determining health of an actuator that includes applying power to an actuator operating in a nominal operational state, capturing a first signal representative of actuator movement or actuator position, capturing a second signal representative of total actuator force, determining, based on the first signal, an inertial force value representative of force used to overcome at least one of inertia of the actuator and inertia of a load on the actuator, determining, based on the inertial force value and the captured second signal, a load force value representative of actuator force used to overcome force of the load and friction of the load, determining a health value of the actuator based on the load force value, and providing an indication of health of at least one of the actuator and the load.
