The invention relates to an automatic rigging arrangement for an actuation system wherein the rigging arrangement includes in combination a differential length feedback device that has a moveable inner member and an outer member, with the outer member secured at its ends respectively to a power drive unit and an actuator, the moveable inner member being controllingly coupled to a power drive control and secured to an actuator position feedback member of the actuator to thereby provide via the moveable member of an actuator position feedback input signal to a signal summing means associated with the power drive control. The feedback input signal being proportional to an actuator position and the signal summing means being responsively coupled to the power drive unit to receive as an input, a signal representative of a given position commanded. The signal summing means having an output that is a function of the signal representative of the position commanded and the feedback signal with the signal summing means output controls the power drive unit and therefore the actuator irrespective of the actuator and its mounting position in respect of the location of the power drive unit.
