DOI: 10.1080/00207179.2017.1308557
Abstract: ABSTRACT The present paper deals with the identification of nonlinear mechanical vibrations. A grey-box, or semi-physical, nonlinear state-space representation is introduced, expressing the nonlinear basis functions using a limited number of measured output variables. This… read more here.
