Simple techniques for the identification and control of semi-active dampers

The main purpose of this paper is to describe how standard spectral analysis techniques can provide an efficient and easy to interpret method for the characterisation and identification of semi-active dampers. The paper begins with a brief description of the spectral analysis algorithms, followed by detailed simulation examples to demonstrate their use. The focus throughout is on the techniques ability to provide an intuitive insight into a systems behaviour and the ease with which a priori knowledge and various modelling strategies can be incorporated.
