Since the rigidity of miniaturized and lightened mechanism becomes low, mechanical vibration occurs at the multiple modes. The vibrational modes are changed by the operational condition. Thus, it is necessary to estimate these vibrational modes in real-time to achieve the damping control. In this series of cooperative research, an adaptive observer based on the delta form was proposed. This paper examines the feasibility of the implementation of this observer to fixed-point microprocessors. As an illustration, first-order-systems are considered. In the case of 8 bit word length, overflow and underflow occurs in this calculation and the adaptive system becomes unstable. In the case of 16 bit word length, the proposed observer can follow the time-varying plant parameters in real-time. Simulation results show that the proposed method can be implemented to fixed point microprocessors.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA12210629","subitem_source_identifier_type":"NCID"}]},"item_1_text_2":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_text_value":"論文"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Article"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京都立産業技術高等専門学校ものづくり工学科電気電子工学コース"},{"subitem_text_value":"産業技術大学院大学"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2014-03-01"}],"displaytype":"detail","filename":"KJ00009651765.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"KJ00009651765","url":"https://metro-cit.repo.nii.ac.jp/record/161/files/KJ00009651765.pdf"},"version_id":"276af0e0-1531-458f-998b-beff4abb2975"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"System identification","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Delta operator","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Digital controller","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Microprocessor control","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"固定小数点演算に基づいた適応型オブザーバ ～固定小数点マイクロプロセッサへの実装に関する課題 ～","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"固定小数点演算に基づいた適応型オブザーバ ～固定小数点マイクロプロセッサへの実装に関する課題 ～"},{"subitem_title":"Adaptive Observer Based on Fixed-Point Arithmetic ?
