The modification requires the structural modes to be generated with fictitious inertia terms at structural degrees of freedom that represent the relative control-surface rotation angles. The resulting modes can accurately accommodate the concentrated hinge moments applied by the actuators, hence be used in a direct-force approach that avoids the generation of control modes and the associated inertial and aerodynamic matrices. The direct-force approach does not require the standard 3rd-order linear actuator models, which facilitates the introduction of nonlinear elements at any part of the actuator model. The increased-order modeling method, utilized in the Dynresp code, is used in a comparative investigation between the control-mode and direct-force approaches. The sample application is based on the Green Regional Aircraft model developed by Alenia Aermacchi for the development of loads alleviation control laws in the Clean Sky 1 project.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/11\/IFASD-2015-054.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Rami Veiberman, Martin Weiss, Moti Karpel<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: IFASD-2015-054<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2413,2414],"tags":[],"class_list":["post-18408","post","type-post","status-publish","format-standard","hentry","category-1-ifasd-2015","category-aeroservoelasticity-1-ifasd-2015","category-2413","category-2414","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18408","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=18408"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18408\/revisions"}],"predecessor-version":[{"id":18410,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18408\/revisions\/18410"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=18408"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=18408"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=18408"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
