Next seminar: Optimizing active control solutions for vibration mitigation of structures
Active control systems are in principle very effective for vibration mitigation of structures subjected to wind and earthquake. Despite of the existence of documented full-scale applications of active control, notably in Japan, several issues need to be addressed in order to gain a wider acceptance of smart technologies by owners and designers. The main issues can be roughly summarized as: proper design and modeling of the actuators, optimal sensors placement and use of efficient calculators and data transmission protocols to reduce time delay; proper modeling of control-structure-interaction effects; definition of appropriate control algorithms able to deal with model uncertainties and physical constraints.
The aim of this talk is to expose ongoing research that the presenter is leading on active control solutions for structural vibration mitigation. Several specific aspects of the general topic are treated, like optimal actuators' and sensors' distribution for 3D response mitigation, proper reproduction of experimental actuators' dynamics, management of physical limits of devices, exploitation of robust adaptive control strategies for multi-hazard vibration mitigation.
Dr. Ilaria Venanzi is currently Assistant Professor at the Department of Civil and Environmental Engineering of University of Perugia. She received the Ph.D. in Civil Engineering in 2006 and was post-doc from 2006 to 2009 at the Department of Civil and Environmental Engineering, University of Perugia.
