This method requires the vessel to operate at a constant low speed because the depth of the trawl must be kept constant. In addition, the operation is often conducted by a small number of people, who must simultaneously maneuver the vessel and fish, making automation desirable. To develop this device, a mathematical model of the vessel was created based on data collected from actual operation of the vessel, and simulations were conducted to determine what type of control system would be suitable. As a result, it was possible to grasp effective control methods, effects of disturbances such as tides and waves, and how to deal with effective parts to improve response.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "MDPI AG", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.3390/automation3040027"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2673-4052", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Haruhiro Shiraishi", "creatorNameLang": "ja"}, {"creatorName": "Haruhiro Shiraishi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Hajime Shiraishi", "creatorNameLang": "ja"}, {"creatorName": "Hajime Shiraishi", "creatorNameLang": "en"}]}]}, "item_title": "Development of a Speed Control Device for Fishing Vessels at Low Speeds and Simulation of the Control System", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Development of a Speed Control Device for Fishing Vessels at Low Speeds and Simulation of the Control System", "subitem_title_language": "ja"}, {"subitem_title": "Development of a Speed Control Device for Fishing Vessels at Low Speeds and Simulation of the Control System", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "7", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/7307", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2025-09-01"}, "publish_date": "2025-09-01", "publish_status": "0", "recid": "7307", "relation": {}, "relation_version_is_last": true, "title": ["Development of a Speed Control Device for Fishing Vessels at Low Speeds and Simulation of the Control System"], "weko_shared_id": -1}
