| Abstract: |
The research undertaken in this paper implements Multiple-input Multiple-output Active Aeroelastic Control, on a flexible wing system. Two separate configurations of the wing are investigated: 1) The linear case, where the MIMO adaptation of the Receptance Method is implemented to achieve pole-placement, ultimately to provide increased stability in the vicinity of flutter, 2) The structurally nonlinear case, where Feedback Linearisation is applied to essentially cancel the existing system dynamics and prescribe new (linear) dynamics via feedback, also to improve stability at higher airspeeds, particularly close to flutter. Furthermore, closed-loop performance is investigated for both the above cases in the presence of gust inputs of varying gust profile. The two inputs to the system are actuated trailing and leading-edge flaps located on the outermost sector of the wing. The initial experimental campaigns will focus on case 1 above. Preliminary closed-loop experiments on the linear wing, in the single-input case indicate good control authority of the trailing edge flap |
