Nonlinear Dynamics and Control of Wings and Panels.

Abstract

A multidisciplinary team of experts in aeroelasticity, control and nonlinear dynamics will study experimentally and theoretically the control of prototypical aeroelastic systems. Emphasis will be given to those systems with significant nonlinear characteristics, e.g. freeplay structural behavior and aeroelastic stall behavior for airfoils and wings and geometrical structural behavior and aeroelastic stall behavior for airfoils and wings and geometric structural nonlinearities of panels (plates and shells). Research in nonlinear dynamics has reached a level of relative maturity such that applications to real engineering systems (including physical experiments) are the next major advance. Adaptive control strategies will be employed to attenuate both persistent and impulsive disturbances for nonlinear mechanical and aeroelastic systems will be used co aid in the design of distributed control structures with a focus on model-intensive control algorithms.
