Application of frequency domain adaptive infinite impulse response filtering for identification of flexible structure dynamics

Research output: Contribution to journalArticle


The identification problem of transfer functions associated with flexible structures is addressed in this paper. An adaptive infinite impulse response filter with data preprocessing in the frequency domain is used to identify directly the poles of the transfer function and the coefficients of the numerator polynomial. The parallel form realisation is utilised to model the structure of the identified transfer function. The stability of the identified system can easily be monitored and the sensitivity of its coefficients is lower compared to that of the classical direct form. Simulation studies are used to illustrate the proposed algorithm.
