This drive circuit consists of a DDS and several high-voltage operational amplifiers to generate a sine wave. This circuit makes it possible to change the values of the three parameters that control the rotation speed of the ultrasonic motor at high speed and arbitrarily. In conventional control methods, the rotational speed of the ultrasonic motor is varied by changing the frequency. However, there is a characteristic in which the control input value is not correctly reflected in the output value in the extremely slow rotation speed range. The proposed variable frequency and voltage control method enables the output value to be correctly reflected in relation to the control input value. Using these methods, high-precision positioning control was achieved.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C); 研究期間：2019～2021; 課題番号：19K04337; 研究分野：電子回路; 科研費の分化・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ(WEKO2)","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"oka, masato"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学工学部; 教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"岡, 正人"},{"creatorName":"オカ, マサト","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-12-05"}],"displaytype":"detail","filename":"19K04337seika.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"19K04337seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/23243/files/19K04337seika.pdf"},"version_id":"834d4ee2-1030-4a7f-b45f-fe5499400c8c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ultrasonic motor","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Precise position control","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Piezoelectric element","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Actuator","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"パルス幅高速切換え方式による超音波モータの精密位置決め制御回路の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"パルス幅高速切換え方式による超音波モータの精密位置決め制御回路の開発","subitem_title_language":"ja"},{"subitem_title":"Development of precision positioning control circuit of ultrasonic motor by pulse width high speed switching method","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4819"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-12-05"},"publish_date":"2022-12-05","publish_status":"0","recid":"23243","relation_version_is_last":true,"title":["パルス幅高速切換え方式による超音波モータの精密位置決め制御回路の開発"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-31T08:00:09.618117+00:00"}
