The use of statistical high frequency vibration models for passive and active control system design
by Prof. Robin Langley, University of Cambridge, United Kingdom (Short bio here: https://www.eng.cam.ac.uk/robinlangley )
Abstract
It is well known that the prediction of the medium to high frequency vibroacoustic response of an engineering system can pose severe computational difficulties, due to both the large number of degrees of freedom required in a model and the sensitivity of the response to small random manufacturing variabilities. These difficulties have led to the development of analysis techniques which are inherently statistical, such as Statistical Energy Analysis (SEA), which seeks to predict the mean and variance of the energy of the response, averaged over regions, or subsystems. Such methods are clearly useful in the design of passive vibration control: the response can simply be recalculated for various design changes (for example, the addition of soundproofing) and an optimal combination of performance and cost can be sought. However, these methods are not normally associated with the design of active control systems, since the phase of the response is not predicted by the approach. It is shown here that progress can be made towards employing high frequency methods in active control design by considering hybrid deterministic-statistical models and/or a property known as the analyticity-ergodicity condition.
