Damage Tolerant Active Contro l: Concept and State of the Art
Damage tolerant active control is a new research area relating to fault tolerant control design applied to mechanical structures. It encompasses several techniques already used to design controllers and to detect and to diagnose faults, as well to monitor structural integrity. Brief reviews of the common intersections of these areas are presented, with the purpose to clarify its relations and also to justify the new controller design paradigm. Some examples help to better understand the role of the new area.

GENARI, Helói F.G; MECHBAL, Nazih; COFFIGNAL, Gérard; NOBREGA, Euripedes (Elsevier, 2017)A new approach for vibration reduction of flexible structures subject to damage is here proposed, based on modal H∞H∞-norm control. Considering that structural damage provokes different effects on each vibration mode, the ...
