Distributed State Feedback Control for Aeroelastic Morphing Wing Flutter Supression

摘要

This paper offers a novel approach at flutter suppression problem on morphing wing and relates to current research of morphing aircraft. The active flutter suppression task is formulated as a state synchronization in a network of identical Linear Time-Invariant (LTI) systems. These systems consist of wing segments which can be actuated separately. Finite Element Method (FEM) approach and unsteady aerodynamics represented by Theodorsen function are used for flexible morphing wing modeling. An example of distributed Linear-Quadratic Regulator (LQR) state synchronization is shown in this paper. Comparison in time-domain, frequency-domain, and flutter speeds has been done for the system with distributed LQR and the original system.
