In this study, a frequency domain data-driven fixed-order [Formula: see text] controller synthesis approach is introduced to solve above mentioned problem for linear systems. In our approach, the generalized plant is identified by using experimental data obtained from closed-loop tests. The transfer function of the structured [Formula: see text] controller is synthesized by using only the frequency response of the plant without the need of a parametric model. The presented approach is verified experimentally for position control of an electromechanical control actuation system with proportional-derivative (PD) type controller.<\/jats:p>","DOI":"10.1177\/0142331219847741","type":"journal-article","created":{"date-parts":[[2019,5,23]],"date-time":"2019-05-23T03:21:50Z","timestamp":1558581710000},"page":"1059-1067","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Data-driven fixed-order\n                    <i>H<\/i>\n                    <sub>\u221e<\/sub>\n                    controller synthesis in frequency domain: Closed-loop system approach"],"prefix":"10.1177","volume":"43","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1291-3803","authenticated-orcid":false,"given":"Ersin","family":"Da\u015f","sequence":"first","affiliation":[{"name":"T\u00dcB\u0130TAK SAGE, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Selahattin","family":"\u00c7a\u011flar Ba\u015flam\u0131\u015fl\u0131","sequence":"additional","affiliation":[{"name":"Hacettepe University, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,5,23]]},"reference":[{"key":"bibr1-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-1684(99)00039-0"},{"key":"bibr2-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1080\/002071799220830"},{"key":"bibr3-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1109\/MCS.2006.1636313"},{"key":"bibr4-0142331219847741","doi-asserted-by":"publisher","DOI":"10.3182\/20060705-3-FR-2907.00059"},{"key":"bibr5-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1016\/S0005-1098(02)00032-8"},{"key":"bibr6-0142331219847741","author":"Da\u015f E","year":"2018","journal-title":"Transactions of the Institute of Measurement and Control"},{"key":"bibr7-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1177\/1077546316672974"},{"key":"bibr8-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1016\/S0005-1098(99)00022-9"},{"key":"bibr9-0142331219847741","doi-asserted-by":"publisher","DOI":"10.3182\/20110828-6-IT-1002.00708"},{"key":"bibr10-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1002\/acs.714"},{"key":"bibr11-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1080\/00207179108953619"},{"key":"bibr12-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1201\/b15752"},{"key":"bibr13-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2012.07.014"},{"key":"bibr14-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1016\/j.automatica.2010.05.019"},{"key":"bibr15-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1002\/acs.825"},{"key":"bibr16-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1002\/rnc.3594"},{"key":"bibr17-0142331219847741","doi-asserted-by":"publisher","DOI":"10.1016\/j.automatica.2014.06.001"},{"key":"bibr18-0142331219847741","unstructured":"Ljung L (1999) System identification - Theory for the User 2nd edition PTR.
