DESIGNING LOW-ORDER MODELS WITH PRESCRIBED POLES AND ZEROS.

Research output: Contribution to journalArticlepeer-review

Abstract

It was recently suggested that reduced-order modeling might be better effected if carried over a frequency interval by means of generalized Pade approximations using modified Chebyshev polynomials. It is shown that these reduction techniques enable the design of low-order models whose poles and zeros are a priori specified. In particular, the proposed method turns out to generalize modal reduction techniques.
