چکیده:

In this paper, Greybox technique is used for identification of a cantilever wing model in a subsonic incompressible flow. The purpose of this study is to investigate the wing’s aeroelastic behavior and to get unknown parameters in its governing equations. Time response of the wing is obtained through the governing analytical equations of the wing model and then, System Identification is done through these responses from governing equations, using MATLAB System Identification Toolbox. The results show that the identified parameters are in a good accordance with the real data and as a result, with these values inserted in the equations, identified system response is acceptably close to the response of real system.
