Identification techniques are used to compute aerodynamic transfer functions on a 3 dof airfoil. The aerodynamic response of the aeroelastic system is obtained from the unsteady Euler equations. Radial Basis Functions are used to execute the mesh motion. A LQR controller is designed to delay the flutter boundaries on the aeroservoelastic system using the identified aerodynamic transfer functions.
