This chapter briefly covers the essential methods to be employed in deriving a suitable aeroelastic plant model. Aeroservoelastic (ASE) analysis and design begins with a plant model that is simple and yet captures the essential dynamical features. An ASE plant model is based on linear structural dynamics and unsteady aerodynamics, both of which can be described either by linear operational forms or integral equations. The baseline structural model is derived either by the Newtonian or the Lagrangian method and has aerodynamic forces and moments as the unknown driving functions of the generalized coordinates. The simplest unsteady aerodynamic model is for the inviscid flow. Such a flow is termed the ideal flow, because it can yield closed‐form solutions. Once the aerodynamic transfer function is obtained by rational function approximation (RFA), the equations of motion of the aeroelastic plant can be expressed in the Laplace domain.
