Most of such applications adopt feedforward control based on LMS algorithm. Feedback control, on the contrary, has been less used, because it often causes the unstable oscillation called howling. The author has proposed the new approach of feedback control in which the phase of the loop transfer function is suitably adjusted so as to avoid the system instability. This paper describes the principle of the control method and the comparison between the theoretical estimations and experimental results.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.57375/00000390","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"福井工業大学"}]},"item_10002_relation_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"TF00008849","subitem_relation_type_select":"NCID"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2868571","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"林, 卓郎"}],"nameIdentifiers":[{"nameIdentifier":"9812","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hayashi, Takuro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"9813","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-04-12"}],"displaytype":"detail","filename":"KJ00004279687.pdf","filesize":[{"value":"569.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004279687.pdf","url":"https://fut.repo.nii.ac.jp/record/396/files/KJ00004279687.pdf"},"version_id":"30cd8d0e-ee8a-42a3-8251-2859da6fbdfc"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"周期音に対するフィードバック型ANCシステムの研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"周期音に対するフィードバック型ANCシステムの研究"},{"subitem_title":"A study on ANC System using feedback control for periodic noise","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"2","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-04-04"},"publish_date":"2009-04-04","publish_status":"0","recid":"396","relation_version_is_last":true,"title":["周期音に対するフィードバック型ANCシステムの研究"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-20T14:33:23.813834+00:00"}
