ABSTRACT:
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.
