Abstract

The dynamic aeroelastic response of aircraft wings in an incompressible flow and their robust control, when exposed to gust and explosive type loads are examined. The structural model in the form of a thin-walled beam incorporates a number of non-classical effects, such as transverse shear, material anisotropy, warping inhibition, and rotatory inertia. The unsteady incompressible aerodynamics loads are expressed in the time domain, and are based on von Karman-Searsaero dynamic model. The study is carried out via implementations of the Linear Quadratic Gaussian(LQG) control methodology with sliding mode observer. The influence of aeroelastic effect on the response and its robust control are investigated and a number of conclusions are outlined.
