Flight control law design for improving handling qualities is one of them because the major problem in the design of controllers then concerns aeroservoelastic stability. To deal with this dif\ufb01culty, methodologies for \ufb02ight control law design considering the aeroelastic dynamics of the aircraft are being pursued. In this paper, an output-feedback-based stability augmentation system is proposed and designed to improve the handling qualities of a \ufb02exible aircraft and to increase the structural damping of some of its aeroelastic modes. The design is based on the projective control technique, which allows preserving in the closed-loop system the eigenstructure of certain modes of interest whose dynamic characteristics stem from an optimal state feedback solution. The X-HALE \ufb02exible aircraft is considered. Numerical studies by means of nonlinear simulations allow testing and con\ufb01rming the effectiveness of the proposed controller.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/12\/IFASD-2019-012.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Rafael M.
