Iterative Adaptive Control of a Three Degrees-of-Freedom Aeroelastic Wing Model

Abstract:

The aeroelastic wing model is an underactuated 3 Degrees-of-Freedom (DoF) system in which only a single control signal can be applied. Its model-based control attracted much attention recently. In the present contribution the effects of 20% modeling error in two significant system parameters are investigated in PI and P-type controllers that can be made adaptive by the application of Robust Fixed Point Transformations (RFPT). It is shown that by the use of this simple adaptive technique operating with altogether 4 control parameters precise control of the trailing-edge surface deflection is possible. This statement is substantiated by simulation results.
