Control structure interaction of electromagnetic mass damper system for structural vibration control / Chunwei Zhang in Journal of engineering mechanics, Vol. 134 N°5 (Mai 2008) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 134 N°5 (Mai 2008) . - pp. 428–437 Titre : Control structure interaction of electromagnetic mass damper system for structural vibration control Type de document : texte imprimé Auteurs : Chunwei Zhang, Auteur ; Jinping Ou, Auteur Année de publication : 2008 Article en page(s) : pp. 428–437 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Vibration  Damping  Control  systems  Shake  table  tests  Structural  control  Interaction  models Résumé : To investigate the effect of control-structure-interaction (CSI) between the innovative electromagnetic mass damper (EMD) control system and the test structure, three computational models are first developed in this paper. Then, typical driving voltages are applied to the servo-amplifier of the EMD system to excite the structure and to examine the dynamic behavior of the EMD system when it is implemented into the structure. Furthermore, the test results are compared with the predictions based on the proposed parametric models, namely on-line examination. Finally, shaking table tests of structural seismic response control employing the EMD control system are conducted to validate and compare the effectiveness of those parametric models. All the test results have shown that only when the CSI effect (especially the higher-order CSI effect) is fully considered, can the on-line dynamical property of the EMD system be accurately predicted and its control performance fully exerted. This is essential to achieve the highest performance when employing such EMD systems in suppressing structural vibrations.
