The present work is devoted to the design, realization and testing of the control surfaces actuation system that will be implemented in a wind tunnel aeroelastic model within the GLAMOUR project. Such a scaled aircraft is equipped by three movable surfaces (two ailerons and one elevator) employed to suppress aeroelastic vibrations due to incoming gusts. A control approach based on standard industrial PID regulators, tuned by a novel frequency– based optimization, is taken into consideration, thanks to its simplicity and intrinsic robustness. Numerical results are presented with the aim of validating this methodology, considering both standard input signals and realistic command profiles. It is found out that an integrated observer for disturbance rejection is required to satisfy one of the required constraints. Finally, the preliminary realization of the test rig is described.
