A theoretical study to utilize the recent advances in structural dynamic analysis, unsteady-aerodynamic theories, control theories and optimization techniques in the design and analysis of flutter suppression systems was conducted. At the present time the best formulation of the problem is still open to question, therefore, the formulations that appear most promising for design study applications are presented. One class of formulation presented is more suitable to a parameter optimization design approach in the frequency domain while the second is more suitable to optimal control design techniques. Some of the inherent difficulties associated with casting the problem in the optimal control form are illustrated.
