The key concept of the new method is explicit treatment of the characteristics of the actuators: power limit and delay of response. Actuators with the newly developed control criterion can work even under extremely large seismic loading. In order to achieve the objectives, the classical theory of optimal control is applied and optimality conditions of operation of the actuators are obtained. A solution procedure is proposed for one-degree-of-freedom system, and a concise control criterion is derived. The controllability of the proposed procedure is investigated by a synthesis procedure. Next, the case of a delayed actuator is studied by modeling it with a first-order differential equation, and a similar concise criterion is obtained. Finally, the efficiency of the present method is examined by means of numerical simulation. The result shows high efficiency of the proposed method in suppressing the excessive vibration responses, in comparison to the classical regulator method.","subitem_description_type":"Abstract"},{"subitem_description":"地震時の構造物の振動をアクティブに抑制する一つの効率的な手法を提案する.その基礎となる考え方は,出力限界や応答遅れなどアクチュエータの能力の制約を精密に扱うことにある.この新しい制御規範によって駆動されるアクチュエータは,巨大地震時にも正常に作動することができるという利点をもつ.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"127219","nameIdentifierScheme":"WEKO"}],"names":[{"name":"東原, 紘道"}]},{"nameIdentifiers":[{"nameIdentifier":"127220","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Indrawan, Benjamin"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032745","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162258","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Higashihara, Hiromichi"}],"nameIdentifiers":[{"nameIdentifier":"127217","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Indrawan, Benjamin"}],"nameIdentifiers":[{"nameIdentifier":"127218","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":"2017-06-26"}],"displaytype":"detail","filename":"ji0663003.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0663003.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32745/files/ji0663003.pdf"},"version_id":"8c326cd6-088d-41c4-a640-fcef3f57633f"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Efficient Active Suppression of Vibration Based upon Explicit Treatment of Actuator Characteristics","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Efficient Active Suppression of Vibration Based upon Explicit Treatment of Actuator Characteristics","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["4721","4722"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32745","relation_version_is_last":true,"title":["Efficient Active Suppression of Vibration Based upon Explicit Treatment of Actuator Characteristics"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:17:26.477626+00:00"}
