This chapter introduces the process of aeroservoelasticity (ASE) design. ASE applications require designing an underlying feedback control system in order to ensure closed‐loop stability in a range of operating conditions. Such a design is typically based upon a linearized model of the underlying aeroelastic system. The computation of unsteady aerodynamic forces from structural degrees of freedom is the main problem in aeroelastic modelling. An important step in ASE design is to derive a baseline multivariable feedback controller for active stabilization by standard linear closed‐loop techniques, such as eigen structure assignment and linear optimal control. Any aeroelastic model employed in ASE design is likely to have modelling uncertainties in its parameters. The chapter explores various adaptation mechanisms that can be applied to adaptive ASE design. Alternatives to the nonlinear geometric feedback methods are the Lyapunov stabilization techniques of passivity‐based methods and recursive back‐stepping integration.
