N2 - A novel algorithm for identification of unknown structural parameters in flexible boosters is presented here. In this method, first of all coefficient matrices in recursive form are estimated based on sensor outputs, which is followed by identifying structural parameters utilizing matrix relations between those and system description form. This algorithm is relatively robust and promising, since neither modal coordinates nor state reconstruction is required, in which tremendous amount of efforts have to be concentrated to. Numerical discussion here was carried out and it demonstrated its practical effectiveness.
