Abstract. In this work a flutter suppression system design based on simple adaptive control architecture and an alternative beam finite element modelling of wings equipped with trailing edge control surfaces is proposed. The aeroelastic beam finite element used is based on Euler-Bernoulli beam theory for the flexural behavior, De Saint Venant theory for torsion and two-dimensional time-domain unsteady aerodynamics applied by means of strip theory assumptions. The finite element modeling used allows to write the aero-servo-elastic plant governing equations in state-space form, from which the flutter suppression system design can be carried out in a time domain fashion. The simple adaptive control architecture has been applied to the aero-servo-elastic plant which passivity requirement has been enforced implementing a parallel feed-forward compensator.
