Apparatus and methods for hybrid actuation and suppressing vibration are
disclosed. In one embodiment, a hybrid actuator includes a first actuator
and a second actuator linked to move a component a combined actuation
distance. The first actuator may include a hydraulic piston, and the
second actuator may include a piezo-electric actuator. In another
embodiment, the first actuator is activated within a first frequency
range, and the second actuator is activated within a second frequency
range. In another aspect, a method is provided combining a first
actuation movement and a second actuation movement. In another
embodiment, a system is provided for suppressing movement of a component
including a combination of actuators. In a further embodiment, an
aircraft is provided with hybrid motion suppression including a first
actuator and a second actuator linked to activate a control surface.
