Optimal and robust design of a control surface actuation system within the GLAMOUR project

Alessandro De Gaspari, Francesco Toffol, Paolo Mantegazza, Andrea Mannarino


The present work is related to the design of the control surfaces actuation system that has been installed on a wind tunnel aeroelastic model within the GLAMOUR project. Such a scaled aircraft is equipped with two ailerons and an elevator, used to alleviate vertical gust loads.
A control scheme, based on PID regulators, is taken into consideration, thanks to its simplicity.
It was tuned through two different methodologies: an unfalsified frequency-based optimization and a Quantitative Feedback Theory (QFT) approach.
Numerical results are presented, comparing the adopted methodologies, considering both simple input signals and realistic command profiles.
