In order to satisfy agility requirement, a Control Momentum Gyro (CMG) is being focused on as a powerful torquer. A CMG has a flywheel mounted in a gimbal frame that can be rotated about the gimbal axis. In some gimbal angle configurations, the direction of torque generated by CMGs is restricted. These are called singularity states, and the singularity avoidance problem has been discussed in many papers. In this paper, a steering law based on manipulability is presented as a means of singularity avoidance. First, the manipulability of CMGs is determined. Next, a spacecraft control method and gimbal steering law are manipulated. Finally, the effectiveness of this law is verified.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0046652029","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/ISAS)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0918-8053","subitem_source_identifier_type":"ISSN"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙開発事業団"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Space Development Agency of Japan"}]},"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":"川井, 洋志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawai, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"特異回避","subitem_subject_scheme":"Other"},{"subitem_subject":"マニピュラビリティ","subitem_subject_scheme":"Other"},{"subitem_subject":"ステアリング制御則","subitem_subject_scheme":"Other"},{"subitem_subject":"CMG","subitem_subject_scheme":"Other"},{"subitem_subject":"運動量","subitem_subject_scheme":"Other"},{"subitem_subject":"制御理論","subitem_subject_scheme":"Other"},{"subitem_subject":"フライホイール","subitem_subject_scheme":"Other"},{"subitem_subject":"ジンバル","subitem_subject_scheme":"Other"},{"subitem_subject":"singularity avoidance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"manipulability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"steering control law","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"CMG","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"momentum","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"control theory","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flywheel","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gimbal","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Singularity avoidance steering control law for Control Momentum Gyro system based on manipulability","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Singularity avoidance steering control law for Control Momentum Gyro system based on manipulability","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1560","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"7730","relation_version_is_last":true,"title":["Singularity avoidance steering control law for Control Momentum Gyro system based on manipulability"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:34:56.946872+00:00"}
