Active devices, while providing significant reductions in structural motion, typically require large (and often multiply-redundant) power sources, and thereby raise concerns about stability. Passive devices are fixed and cannot be modified based on information of excitation or structural response. Semiactive devices on the other hand can provide significant vibration reductions comparable to those of active devices but with substantially reduced power requirements and in a stable m 606 $aVibration 606 $aDamping (Mechanics) 606 $aStructural control (Engineering) 615 0$aVibration. 615 0$aDamping (Mechanics) 615 0$aStructural control (Engineering) 676 $a624.171 676 $a624.176 700 $aCasciati$b Fabio$031624 701 $aMagonette$b Georges$01615774 701 $aMarazzi$b Francesco$01615775 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910830336003321 996 $aTechnology of semiactive devices and applications in vibration mitigation$93946126 997 $aUNINA
