The H\u221e optimal method and \u03bc synthesis are applied to the robust control law design for gust load alleviation (GLA) problem. Specifically, with instability risk introduced in the uncertain model, the GLA factor can be largely increased. The instability probability for a uncertain system and nominal GLA factor are trade-off to get a higher performance and acceptable instability risk. At the same flow velocity, the stability robustness is decreased while the nominal gust load can be largely alleviated. Vise visa, though the nominal aeroelastic model is stable at all the velocities between 10 m\/s to 30 m\/s, the instability risk increased with the GLA factor ascending. Results indicate that with introducing a 0.2% instability risk, the nominal gust load can be alleviated by 24.5%.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/11\/IFASD-2015-077.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Yuting Dai, Chao Yang, Chaolei Wang<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: IFASD-2015-077<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2413,2429],"tags":[1972,2086,2592,2591],"class_list":["post-18463","post","type-post","status-publish","format-standard","hentry","category-1-ifasd-2015","category-loads-alleviation","tag-aeroelasticity","tag-gust-load-alleviation","tag-probability","tag-robust","category-2413","category-2429","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18463","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=18463"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18463\/revisions"}],"predecessor-version":[{"id":18465,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18463\/revisions\/18465"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=18463"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=18463"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=18463"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
