This twin concept combines physics-based models within a model order reduction framework—to obtain real-time feedback rates—and data science. Thus, the main idea of the HT is to develop on-the-fly data-driven models to correct possible deviations between measurements and physics-based model predictions. This paper is focused on the computation of stable, fast, and accurate corrections in the HT framework. Furthermore, regarding the delicate and important problem of stability, a new approach is proposed, introducing several subvariants and guaranteeing a low computational cost as well as the achievement of a stable time-integration. 000119019 536__ $$9info:eu-repo/grantAgreement/ES/MINECO-CICYT/DPI2017-85139-C2-1-R$$9info:eu-repo/grantAgreement/ES/UZ/ESI-ENSAM-Simulated Reality 000119019 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000119019 594__ $$a1.6$$b2021 000119019 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000119019 700__ $$aCameron, Morgan 000119019 700__ $$aLe Peuvedic, Jean-Marc 000119019 700__ $$aGroulier, Juliette 000119019 700__ $$aDuval, Jean-Louis 000119019 700__ $$0(orcid)0000-0003-1017-4381$$aCueto, Elias$$uUniversidad de Zaragoza 000119019 700__ $$aChinesta, Francisco 000119019 7102_ $$15004$$2605$$aUniversidad de Zaragoza$$bDpto.
