Parameter estimation and system identification are used extensively to obtain dynamic models of engineering systems. A large number of methods have been developed and a huge amount of experience gained in their application, particularly in control engineering and structural dynamics. Although aspects of the methods are different there is a substantial overlap in the methodology and practice used in the identification. These proceedings contain papers authored by researchers and practitioners in the art and science of identification from a range of disciplines and provide an further impetus to the cross fertilisation of ideas in this area.
