The nutational motion of the spacecraft can be detected by the position sensors of the magnetic bearing servo system with a sufficient accuracy without using any of the spacecraft attitude sensors. An intensive cross-coupling method between the two axes to reduce the nutation is proposed and the control system is analyzed in detail. Analytical results and computer simulations show that the nutation damping time constant is shortened by about 1/20 as compared with the gimbal system without cross-coupling effect.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0820000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-820T","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所宇宙研究グループ"},{"subitem_text_value":"航空宇宙技術研究所宇宙研究グループ"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Space Technology Research Group, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Space Technology Research Group, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中島, 厚"}],"nameIdentifiers":[{"nameIdentifier":"472806","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村上, 力"}],"nameIdentifiers":[{"nameIdentifier":"472807","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"NAKAJIMA, Atsushi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"472808","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MURAKAMI, Chikara","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"472809","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":"2020-01-29"}],"displaytype":"detail","filename":"naltr0820t.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr0820t.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45078/files/naltr0820t.pdf"},"version_id":"c6652ea2-0590-4caf-bb10-f2a1496c4630"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"Active Nutation Control of Spacecraft Using a Magnetic Bearing Momentum Wheel with Vernier Gimballing Capability","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Active Nutation Control of Spacecraft Using a Magnetic Bearing Momentum Wheel with Vernier Gimballing Capability","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"45078","relation_version_is_last":true,"title":["Active Nutation Control of Spacecraft Using a Magnetic Bearing Momentum Wheel with Vernier Gimballing Capability"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:45:41.252714+00:00"}
