Unfortunately, the mapping model is difficult to solve by traditional mathematical methods. Therefore, a new approach is proposed by using Recurrent Neural Networks (RNNs) combined the Gated Recurrent Unit (GRU). This method is validated on different structures: a three-degree-of-freedom system and a thin plate. The training dataset is generated by numerical computation methods. The predicted results illustrate that this method has good learning and data prediction ability for stationary and non-stationary time sequences with 20% noise. The applications of this method in the aerospace field will be more mature and have bright prospects in the future.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/hisst-2018_540926.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/hisst-2018_540926.pdf\">Read the full paper &gt; <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Jiaming Zhou , Longlei Dong, \u00a0Guirong Yan<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST 2018-540926<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[71,996,994,198],"tags":[463,464,462,465],"class_list":["post-12938","post","type-post","status-publish","format-standard","hentry","category-papers-aircraft-design","category-high-speed-aerodynamics-and-aerothermodynamics","category-hisst-2018","category-hypersonic-aerodynamics","tag-gated-recurrent-units","tag-mapping-model","tag-recurrent-neural-networks","tag-time-sequence-prediction","category-71","category-996","category-994","category-198","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/12938","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\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=12938"}],"version-history":[{"count":5,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/12938\/revisions"}],"predecessor-version":[{"id":15945,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/12938\/revisions\/15945"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=12938"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=12938"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=12938"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
