The science of aeroservoelasticity (ASE) extends the aeroelastic interactions between aerodynamic forces and a flexible structure, to include a control system. This chapter examines the use of feedback control on a simple binary aeroelastic system with a control surface, and investigates the effects of the control law on the stability and response. In order to examine the stability of the closed loop system, the feedback law must be combined with the basic wing equations. Since the aerodynamic and control terms may be determined for particular reduced frequencies (or frequencies) for a given air speed, it is possible to determine the response to turbulence using a frequency domain representation. As with the frequency domain approach, the effects of frequency‐dependent unsteady aerodynamics and control shaping filters need to be taken into account if accurate models are required.
