VSOP-2 mission requires Astro-G to change its attitude angle for 3 deg in 15 s, and attitude angle error to be less than 0.002 deg after the maneuver, while VSOP-2 mission also requires Astro-G to equip a large deployable antenna. This antenna of 9 m diameter is for VLBI observation and, obviously, should be handled as flexible structure. For these reasons, ACS of Astro-G must have both high-speed and high-precision performance and robustness to uncertainty of flexible structures. In addition, high-speed maneuver mission also requires Astro-G to equip CMGs (Control Momentum Gyros), which have complex mechanism, and therefore need to be studied. In this paper, we studied about Astro-G's ACS with 2 DOF (Degree Of Freedom) control, consists of robust feedbackcontrol and reference with MNME (Modified Nil-Mode-Exciting) profiler, which is based on input shaping and NME profiler. We also studied how to use the CMGs as feedback actuator. The designed 2 DOF control were discussed through numerical simulations.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064733017","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11567475","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学"},{"subitem_text_value":"宇宙航空研究開発機構宇"},{"subitem_text_value":"宇宙航空研究開発機構宇"},{"subitem_text_value":"電気通信大学"},{"subitem_text_value":"電気通信大学"},{"subitem_text_value":"宇宙航空研究開発機構宇"},{"subitem_text_value":"宇宙航空研究開発機構宇"},{"subitem_text_value":"宇宙航空研究開発機構宇"},{"subitem_text_value":"宇宙航空研究開発機構宇"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"University of Electro-Communications (UEC)"},{"subitem_text_language":"en","subitem_text_value":"University of Electro-Communications (UEC)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中邨, 勉"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"坂東, 信尚"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"坂井, 真一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長塩, 知之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"木田, 隆"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"葛西, 時雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山口, 功"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大谷, 崇"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"齋藤, 宏文"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamura, Tsutomu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Bando, Nobutaka","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakai, Shinichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nagashio, Tomoyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kida, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kasai, Tokio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamaguchi, Isao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Otani, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Saito, Hirobumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"柔軟構造を有する人工衛星ASTRO-GのためのCMGの動力学を考慮した高速・高精度姿勢制御の一検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"柔軟構造を有する人工衛星ASTRO-GのためのCMGの動力学を考慮した高速・高精度姿勢制御の一検討"}]},"item_type_id":"5","owner":"1","path":["1555","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"7391","relation_version_is_last":true,"title":["柔軟構造を有する人工衛星ASTRO-GのためのCMGの動力学を考慮した高速・高精度姿勢制御の一検討"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:40:13.989638+00:00"}
