In this work the employment of multiple control surfaces for adaptive flutter suppression systems design of wings is addressed. The aeroelastic plant is modeled taking advantage of an aeroelastic beam finite element framework that relies on an equivalent beam idealisation of the structure and strip theory aerodynamics, including the dynamics of trailing edge control surfaces. A simple adaptive control architecture is employed to realize the flutter suppression systems and the passivity requirement of the aeroelastic plant is ensured by a parallel feedforward compensator implementation. Single and double aileron based flutter suppression systems are investigated and their performance are compared in terms of flutter boundary extension with respect to the open loop case.

Abstract
In this work the employment of multiple control surfaces for adaptive flutter suppression systems design of wings is addressed. The aeroelastic plant is modeled taking advantage of an aeroelastic beam finite element framework that relies on an equivalent beam idealisation of the structure and strip theory aerodynamics, including the dynamics of trailing edge control surfaces. A simple adaptive control architecture is employed to realize the flutter suppression systems and the passivity requirement of the aeroelastic plant is ensured by a parallel feedforward compensator implementation. Single and double aileron based flutter suppression systems are investigated and their performance are compared in terms of flutter boundary extension with respect to the open loop case.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
