AB  - This paper is a numerical investigation on model reduction and controlsystem design of integrally actuated membrane wings. A high-fidelityelectro-aeromechanical model is used for the simulation of the dynamicfluid-structure interaction between a low-Reynolds-number flow and a dielectricelastomeric wing. Two reduced-order models with different levels ofcomplexity are then derived. They are based on the projection of the fullorderdiscretisation of fluid and structure on modal shapes obtained fromeigenvalue analysis and Proper Orthogonal Decomposition. The low-ordersystems are then used for the design of Proportional-Integral-Derivative andLinear Quadratic Gaussian feedback schemes to control wing lift. When implementedin the full-order model, closed-loop dynamics are in very goodagreement with the reduced-order model for both tracking and gust rejection,demonstrating the suitability of the approach. The control lawsselected in this work were found to be effective only for low-frequency disturbancesdue to the large phase delay introduced by the fluid convectivetime-scales, but results demonstrate the potential for the aerodynamic controlof membrane wings in outdoor flight using dielectric elastomers.
