Adaptive Control of Aeroelastic Systems: an Immersion and Invariance Approach

The active suppression of aeroelastic limit cycle flutter oscillations is the main goal of this work. Because of the significant dependence of such outcomes upon flight conditions, an adaptive controller is selected. The related task is accomplished through a full state Immersion and Invariance feedback, embodying linear filters to simplify its design. A practical implementation is then obtained through a sliding mode observer reconstructing the required full state. The effect of different fidelities in the representation of the aerodynamic system will be verified for the classical test case of a typical section in transonic regime.
