On-Demand Aerodynamics in Integrally Actuated Membranes with Feedback Control

This paper is a numerical investigation on model reduction and control system design of integrally actuated membrane wings. A high-fidelity electroaeromechanical model is used for the simulation of the dynamic fluid–structure interaction between a low-Reynolds-number flow and a dielectric elastomeric wing. Two reduced-order models with different levels of complexity are then derived. They are based on the projection of the full-order discretization of fluid and structure on modal shapes obtained from eigenvalue analysis and proper orthogonal decomposition. The low-order systems are then used for the design of proportional–integral–derivative and linear–quadratic–Gaussian feedback schemes to control wing lift. When implemented in the full-order model, closed-loop dynamics are in very good agreement with the reduced-order model for both tracking and gust rejection, demonstrating the suitability of the approach. The control laws selected in this work were found to be effective only for low-frequency disturba...
