For practical applications, the requirements for the ANF are analyzed first, among which the<br>direct acquisition of the frequency estimation is particularly important for the online effectiveness<br>monitoring. Thus, two schemes for the direct frequency estimation, the individual adaptation (IA) and<br>the simultaneous adaptation (SA) based on the recursive maximum likelihood method, respectively, are<br>comprehensively compared. To guarantee that all the frequencies can be estimated precisely under the<br>low signal-to-noise ratio, a strategy of supervising the frequency estimations is proposed for the two<br>schemes. It is concluded that the convergence performance can be improved significantly with such a<br>strategy. Moreover, it is found that the estimation bias of the supervised SA (SSA) is smaller than that<br>of the supervised IA (SIA) both in tracking stationary and time-varying frequencies. Thus, the SSA<br>method is more favourable in practice due to the high precision and robustness. Finally, simulations on<br>a flexible high-speed vehicle are performed to demonstrate the effectiveness of the proposed SSA in<br>the aeroservoelasticity suppression.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-15.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-15.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Minnan Piao, Zhigang Chen, Mingwei Sun, Xinhua Zhang, Zengqiang Chen<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST-2022-15<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1007,1006],"tags":[1038,1042,1040,1041,1039],"class_list":["post-16100","post","type-post","status-publish","format-standard","hentry","category-events","category-guidance-control-systems-hisst-2022","category-hisst-2022","tag-aeroservoelasticity-suppression","tag-direct-frequency-estimation","tag-flexible-high-speed-vehicle","tag-multiple-structural-modes","tag-practical-adaptive-notch-filter","category-993","category-1007","category-1006","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16100","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=16100"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16100\/revisions"}],"predecessor-version":[{"id":16101,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16100\/revisions\/16101"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16100"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16100"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16100"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
