Abstract: In this paper, the features of the methods o! Roger. Vepa Edwards and Karpel are discussed. A proper shortcoming of the three methods is that they are not suitable for engineering practice. Based on the synthesis of the methods of Vepa Edwards and Karpel, an improved approach in which the shortcomings of the aforementioned methods are overcome is proposed by authors of this paper. A numerical example is given. Numerical results show that the aeroelastic system model obtained from the authors' approach can reflect the major characteristics of the system, and therefore the authors' approach is effective and feasible.
