ABSTRACT:
A redundant actuator system in which some of the sub-actuators have a lower force capability than the other sub-actuators. The lower force capability sub-actuators are controlled by a common electrical control circuit while the other sub-actuators are each independently controlled by separate control circuits. A plurality of hydraulic supplies power the sub-actuators, each supply powering one lower force capability sub-actuator, and at least one other sub-actuator.
