Two techniques intended to be used together to suppress vibrations in large, complicated truss structure involve combination of active and passive damping. Based on bridge feedback and criterion for placement of actuators. Research continues to develop system using these and other techniques to suppress vibrations in, and help control shape of, truss structure in outer space that supports precise, segmented reflector of communication antenna. On Earth, developmental techniques applicable to suppression of vibrations in bridges and tall buildings.
