The damping mechanisms associated with #ow/structure interactions are, in general, considered to be non-linear. In this paper, the #uid}elastic instability of a tube in a heat exchanger is controlled using a tunable damper and the sti!ness and damping associated with the #ow-induced non-linearities

Classical force appropriation methods are used in the identi"cation of linear systems to determine the multi-point force vector that will induce single-mode behaviour, thus allowing each normal mode to be identi"ed in isolation. This paper presents an extension to this linear approach that will enab
The bilinear mapping method is very important in designing digital filters from analogue filters for linear systems, because it provides a very simple conversion from a continuous system to a discrete system without introducing aliasing problems. The use of the bilinear mapping method for non-linear
