To reduce the vibrations caused by an impulse force, two active strut members are installed along a vertical of the base bay of the truss. The active strut element consists of a piezoelectric ceramic actuator stack, a force transducer and mechanical interfaces. A self-organizing fuzzy controller (SOFC) is designed to suppress vibration of the truss. The SOFC, which uses the input and output history in its fuzzy rules, is designed to maximize modal damping of a constructed truss structure. Experimental results illustrate that the active piezoceramic strut actuators and the SOFC can effectively reduce vibration of the truss.441-450engActive modal damping controlSelf-organizing fuzzy controller (SOFC)Smart truss structurePiezoelectric stack actuatorsArtigo10.1007/s40430-014-0174-7WOS:000350399200001Acesso restrito79217870480652793283762683761655
