Elements of Aeroservoelasticity
摘要
The basic concepts relating to the application of automatic control systems to improve aeroelastic stability and response characteristics of wing configurations are presented in this chapter. The development of an aeroservoelastic system is illustrated in a two-dimensional configuration consisting of the typical sectionTypical section model that has been extended by the introduction of a movable trailing edge flap (the aileron). The equations that govern the aeroelasticity of the typical section-aileron system are derived and their application is discussed in the context of an optimal controlOptimal control methodology for the synthesis of feedback control laws for stabilisation. The introduction of a state observer is also examined.
