To cite a case, for the Ion-propulsion engine which contributed to the asteroid sample return mission by \"Hayabusa\" spacecraft, it is required to drive at higher voltage in order to get higher specific impulse. However, if the operating voltage becomes higher, the probability of discharge between electronic devices rises and thus the equipment inevitably grows in size to keep sufficient gap between the devices. In addition, as there is no convectional heat transfer in space, the temperature locally becomes very high if the equipment is downsized. So, it can be said that miniaturization and high performance are generally contradictory requirements. In this research, a fluid loop insulation and cooling system was built as a means of realizing both miniaturization and high voltage. For the working fluid of the system, fluorinated inactive liquids were used which can provide high electrical insulation and thermal conductivity. In this paper, it is shown that constructed insulation and cooling system is bilinear system by system identification and wide-range temperature control law for the system was proposed. Finally, the capability of the control law was verified by the experiments and numerical simulation.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064733032","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":"青山学院大学"},{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究本部"},{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Aoyama Gakuin University"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"}]},"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":"杉田, 昌行"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"船瀬, 龍"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森, 治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sugita, Masayuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Funase, Ryu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mori, Osamu","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":"フッ素系不活性液体を用いた流量を操作量とする宇宙用高温高電圧機器の温度制御","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"フッ素系不活性液体を用いた流量を操作量とする宇宙用高温高電圧機器の温度制御"}]},"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":"7406","relation_version_is_last":true,"title":["フッ素系不活性液体を用いた流量を操作量とする宇宙用高温高電圧機器の温度制御"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:40:00.411691+00:00"}
