What is Fluid, structure and control interaction about?

This report summarizes the activities in the use of linear piezoceramic linear actuators coupled with control methods and wing aeroelastic models to increase flutter speeds of wing/store configurations. The work resulted in the successful submission of three journal articles and the completion of three proceedings papers, one invited lecture, and the completion of one PhD dissertation. Our results examine the use of modern control methods (H infinity, loop transfer, LQG/LQR), applied to the wind/store flutter problem as modeled by a typical two-degree-of-freedom airfoil section coupled with the Jones' approximation to the Theodorsen function for the incompressible aerodynamic loads. Physical values are taken from the GBU-UB weapons system mounted on an F-16. Actuator parameters are those of a piezoceramic, linear stroke, wafer device. Store aerodynamics are ignored. Results produce a substantial increase in flutter speed, and allow consideration of the store release problem. Preliminary results and modeling for solving the 3-D version were also investigated
