First, a time-continuous FF control input is derived by the FF control input generation using the time-polynomial (FFT) method, which is the basis of our method. Next, the FF control input derived by the FFT method is approximated using the pulse width modulation (PWM) control input. In this case, the derived FF control input may be unable to suppress the sway of the suspended load because of the modeling error in deriving the FF control input and the quantization error in approximating the FF control input by the PWM control input. To solve these problems, we propose the update type FF control input generation using the time polynomial (UFFT) method, which evaluates the residual sway at a constant time interval and updates the original FF control input derived by the FFT method. Finally, the effectiveness of the UFFT method is confirmed through simulations and experiments. Our method can achieve anti sway transport that reduces the effects of modeling and quantization errors by setting the update frequency of the FF control input and the PWM frequency appropriately. It can search the FF control input that can suppress residual sway even when the control input switching frequency of the controller is not high.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_79_link_17":{"attribute_name":"出版者版へのリンク","attribute_value_mlt":[{"subitem_link_text":"10.1016/j.ymssp.2022.108865","subitem_link_url":"https://doi.org/10.1016/j.ymssp.2022.108865"}]},"item_79_link_5":{"attribute_name":"室蘭工業大学研究者データベースへのリンク","attribute_value_mlt":[{"subitem_link_text":"梶原 秀一（KAJIWARA Hidekazu）","subitem_link_url":"http://rdsoran.muroran-it.ac.jp/html/100000059_ja.html"}]},"item_79_publisher_11":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD","subitem_publisher_language":"en"}]},"item_79_relation_18":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.ymssp.2022.108865","subitem_relation_type_select":"DOI"}}]},"item_79_relation_20":{"attribute_name":"参考URL","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"著者版PDFダウンロード"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/am/pii/S0888327022000619","subitem_relation_type_select":"URI"}}]},"item_79_source_id_12":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0888-3270","subitem_source_identifier_type":"PISSN"}]},"item_79_subject_9":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"548","subitem_subject_scheme":"NDC"}]},"item_79_version_type_21":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"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":"Matsui, Kosuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{}],"affiliationNames":[{},{}]}],"creatorNames":[{"creatorName":"KAJIWARA, Hidekazu","creatorNameLang":"en"},{"creatorName":"梶原, 秀一","creatorNameLang":"ja"},{"creatorName":"カジワラ, ヒデカズ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Feedforward control","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sway control","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Crane","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Crane automation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"PWM control","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Feedforward control input generation method for a crane system with restrictions on drive system","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Feedforward control input generation method for a crane system with restrictions on drive system","subitem_title_language":"en"}]},"item_type_id":"79","owner":"18","path":["46","359"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-01-19"},"publish_date":"2023-01-19","publish_status":"0","recid":"10914","relation_version_is_last":true,"title":["Feedforward control input generation method for a crane system with restrictions on drive system"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-10-20T06:33:50.457614+00:00"}
