A discretization scheme is proposed, and a set of precise basis functions are given in order to obtain a structure-preserving finite-dimensional port- Hamiltonian approximation of the two-dimensional vibro-acoustic system. Using the closed-loop structural invariants of the approximated system an energy-Casimir controller is derived. The performance of the proposed discretization scheme and the controller is shown by means of numerical simulations.<\/jats:p>","DOI":"10.1093\/imamci\/dnaa028","type":"journal-article","created":{"date-parts":[[2020,10,2]],"date-time":"2020-10-02T03:31:21Z","timestamp":1601609481000},"page":"417-439","source":"Crossref","is-referenced-by-count":2,"title":["Structure-preserving discretization and control of a two-dimensional vibro-acoustic tube"],"prefix":"10.1093","volume":"38","author":[{"given":"Ning","family":"Liu","sequence":"first","affiliation":[{"name":"FEMTO-ST, Universit\u00e9 Bourgogne Franche-Comt\u00e9, CNRS, 24 rue Savary, F-25000 Besan\u00e7on, France"}]},{"given":"Yongxin","family":"Wu","sequence":"additional","affiliation":[{"name":"FEMTO-ST, Universit\u00e9 Bourgogne Franche-Comt\u00e9, CNRS, 24 rue Savary, F-25000 Besan\u00e7on, France"}]},{"given":"Yann","family":"Le Gorrec","sequence":"additional","affiliation":[{"name":"FEMTO-ST, Universit\u00e9 Bourgogne Franche-Comt\u00e9, CNRS, 24 rue Savary, F-25000 Besan\u00e7on, France"}]},{"given":"Hector","family":"Ramirez","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Universidad Tecnica Federico Santa Maria, Avenida Espana 1680, Valparaiso, Chile"}]},{"given":"Laurent","family":"Lef\u00e8vre","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Grenoble Alpes, Grenoble INP, LCIS, 26000 Valence, France"}]}],"member":"286","published-online":{"date-parts":[[2020,11,9]]},"reference":[{"key":"2021060309594412500_ref1","doi-asserted-by":"crossref","first-page":"394","DOI":"10.1016\/j.jprocont.2008.07.002","article-title":"Structure-preserving infinite dimensional model reduction application to adsorption processes","volume":"19","author":"Baaiu","year":"2009","journal-title":"J.
