Initially the full order problem is reviewed and conditions regarding the number of sensors/actuators are developed. These investigations are then extended to test setups in which one has an insufficient number of instrumentation on the system, and some methods of obtaining reduced order models are discussed. Effects of commonly used idealizations such as classical damping and diagonal mass matrix are also explored in developing alternate formulations. 000004955 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000004955 653__ $$aIdentification, reduced order models, OKID/ERA 000004955 7112_ $$a15th ASCE Engineering Mechanics Division Conference$$cNew York (US)$$d2002-06-02 / 2002-06-05$$gEM2002 000004955 720__ $$aAngelis, Maurizio De$$iLus, Hilmi$$iBetti, Raimondo$$iLongman, Richard W. 000004955 8560_ $$ffischerc@itam.cas.cz 000004955 8564_ $$s99440$$uhttp://invenio.itam.cas.cz/record/4955/files/610.pdf$$yOriginal version of the author's contribution as presented on CD, . 000004955 962__ $$r4594 000004955 980__ $$aPAPER
