Abstract

The dynamic aeroelastic response and its robust control of aircraft wings modeled as anisotropic composite thin-walled beams in compressible flow and exposed to gust and explosive type loads are examined. The structural model incorporates a number of non-classical effects, such as transverse shear, material anisotropy, warping inhibition, and rotatory inertia. The unsteady compressible aerodynamics for arbitrary small motion in the time domain is based on the concept of indicial functions. The study is carried out via implementations of the Linear Quadratic Gaussian (LQG) control methodology with sliding mode observer. The influence of swept angle and ply angle as passive control on the response and its robust control are specifically investigated and a number of conclusions are outlined.
