Modelling and control of aircraft flutter problem

Abstract

In this paper we develop a state space model for motion of an airfoil in two-dimensional unsteady flow, of an inviscid, incompressible fluid. Then we show that the solution exists, is unique and depends continuously on the initial data. Of particular importance in the context of the present work is the fact that the L-Q-R theory has been extended to such systems and thus may provide appropriate design tools for flutter suppression problems.
