Abstract

This work is a collection and survey of system identification methods in the open literature. The motivation for the work was to find suitable methods of system identification for use in structural diagnosis. Methods surveyed include those which identify the system in terms of modal parameters, and those which identify the system either nonparametrically or in terms of arbitrary parameters. Both deterministic and stochastic methods are reviewed. Particular emphasis is placed on determining damping coefficients, and on a formulation known as modal synthesis. It is concluded that stochastic methods are better suited to the problem of structural diagnosis, and that economic constraints favor the use of modal synthesis methods.
