摘要：

A unified recursive form of the damped complex exponential method is presented, encompassing the features of some well known time-domain identification algorithms. Such a recursive form permits the minimisation of data acquisition and time consumption, but also provides more flexible techniques for problems such as time varying modal parameters and structural control. The problems of using cross correlation data blocks, instead of auto correlation data blocks, for filtering disturbances are considered showing how the conditioning of the information matrix can be affected. Algorithms for computer implementation are given; a special form is derived in order to avoid the inversion of the information matrix at each step of the identification procedures. © 1992.
