Title: Adaptive Strategy To Damage-tolerant Active Control
Abstract: Smart structure development is a recent trend that has been intensely researched, including multidisciplinary new technologies and methods. Damage-tolerant active control is a new research area, applying fault-tolerant control methods to mechanical flexible structures, which demands spatial constraints not commonly found in the general control approach. A proposed strategy, applied to active vibration controller design and considering the possibility to face damage consequences, are here introduced and assessed through finite elements models of healthy and damaged structures, used to simulate achieved performance. A Lamb wave technique is adopted to detect and localize damage, associated to spatial norm controller design and reconfiguration, to attain an acceptable performance to the damaged structure. Results illustrate the pertinent concepts and permit to expect successful application of the proposed approach. © 2015, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd.
