In order to preserve the essence of cluster formation around the earth orbit, both proximity-synchronization avoidance during the control duration and the terminal synchronization are imposed on such a simple linear model. The former corresponds to near-miss avoidance and the latter is imitation of synchronized cluster formation. For two-spacecraft traffic, full avoidance with fuel minimization is expressed by the closed form, which means attainment of all the three requirement: near-miss avoidance, fuel minimization, and automatic control. For three-spacecraft traffic, automatic proximity avoidance by two spacecraft is achieved as the same way. Fuel-minimum avoidance of three-spacecraft proximity is, however, still unsolved. Then, simplified penalty-function guidance is formulated by the piecewise quadratic form.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063480010","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_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"情報通信研究機構"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Information and Communications Technology"}]},"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":"梅原, 広明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Umehara, Hiroaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"衛星誘導","subitem_subject_scheme":"Other"},{"subitem_subject":"区分線形2次制御","subitem_subject_scheme":"Other"},{"subitem_subject":"ニアミス回避","subitem_subject_scheme":"Other"},{"subitem_subject":"クラスター形成","subitem_subject_scheme":"Other"},{"subitem_subject":"最適制御","subitem_subject_scheme":"Other"},{"subitem_subject":"ペナルティ関数","subitem_subject_scheme":"Other"},{"subitem_subject":"燃料消費","subitem_subject_scheme":"Other"},{"subitem_subject":"数学的解析","subitem_subject_scheme":"Other"},{"subitem_subject":"最適化","subitem_subject_scheme":"Other"},{"subitem_subject":"制約条件","subitem_subject_scheme":"Other"},{"subitem_subject":"軌道","subitem_subject_scheme":"Other"},{"subitem_subject":"運動方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"軌道力学","subitem_subject_scheme":"Other"},{"subitem_subject":"satellite guidance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"piecewise linear quadratic control","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"near-miss avoidance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cluster formation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"optimal control","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"penalty function","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fuel consumption","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mathematical analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"optimization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"constraint","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"orbit","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"equation of motion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"orbital mechanics","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":"Multiple-spacecraft clustering by piecewise linear quadratic control","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Multiple-spacecraft clustering by piecewise linear quadratic control","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1558","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"7575","relation_version_is_last":true,"title":["Multiple-spacecraft clustering by piecewise linear quadratic control"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:37:23.864492+00:00"}
