“…To improve the decoupling, additional sensor data away from the interface, commonly called internal dofs [6,25], can be used. More elaborate methods for decoupling can be used, like [23], which uses singular vector decomposition to smooth the processed measured data. Damping identification could be improved by model updating with a numerical model of the system, using the obtained stiffness and damping as a starting point for the optimization process, similar to [22].…”

“…The additional dynamic information can improve the observability, controllability and conditioning of the interface problem. In [4,6,19,21,23,25], extensions of the frequency-based decoupling procedures are presented.…”
