Time-delay will happen during the long distance communication. Therefore, when we have a control object in a long distance, the transmitted reference signal will be delayed certainly. For this reason even though we assume the control object system is a stable, but it will be an unstable system due to existence of time-delay elements. So, we consider the Internal Model Controller method which is one of the robust controllers. Internal Model Controller method is composed of optimum controller and uncertainty model of control object and time-delay elements. The optimum controller is designed by minimizing the coefficients of external disturbance of output signal by H^2 norm in order to stabilize the closed loop system considering the uncertainty of control object and predicted time-delay. Also, in order to compare the performance of the Internal Model Controller, we have compared with Linear Quadratic Integration method. As results the performance of Internal Model Controller was much better than the Linear Quadratic Integration method.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学工学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/24375"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0389-102X"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN0025048X"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学工学部紀要"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2011","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"72","bibliographicPageEnd":"-","bibliographicPageStart":"-"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"NA","subitem_1600292170262":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"No72-2.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2007069/files/No72-2.pdf"},"version_id":"377beeaa-9374-4ab6-af62-508b87882cef"}]},"item_title":"Evaluation of Linear-Quadratic-Integration and Internal Model Control on Application to Wind Turbine Considering Round Trip Delay in Feedback Control System","item_type_id":"15","owner":"1","path":["1642837882018","1642838406845"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-05-15"},"publish_date":"2012-05-15","publish_status":"0","recid":"2007069","relation_version_is_last":true,"title":["Evaluation of Linear-Quadratic-Integration and Internal Model Control on Application to Wind Turbine Considering Round Trip Delay in Feedback Control System"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T03:14:15.656737+00:00"}
