Abstract
An actuator having a nut () co-operating with a screw (); a first cable () coupled to the nut and functionally connected to an output () of the actuator (); and a motor () arranged to drive the screw () in rotation. The actuator also has a mechanism () for comparing the actual position of the nut relative to the frame () with a theoretical position for the nut relative to the frame () in order to obtain a position deviation (δang, δlin) of the nut; and a mechanism () for determining a force applied to the output () of the cable actuator () as a function of the position deviation of the nut. Also disclosed is a method of measuring a force applied to an output () of an actuator (), and to a method of determining prior loading (t) of a cable actuator ().
