Durch eine Simulation auf Basis der Finite-Elemente-Methode (FEM) werden die klassische dynamische Modalzerlegung und eine strukturerhaltende Variante, welche die physikalische Interpretierbarkeit der Zust\u00e4nde beibeh\u00e4lt, miteinander verglichen. Das Problem der optimalen Sensorpositionierung f\u00fcr die Zustandssch\u00e4tzung wird mittels einer Kombination der Konditionszahl der Beobachtbarkeitsmatrix und des dominanten Eigenwertes der Dynamik im nicht-beobachtbaren Unterraum diskutiert. Ein Zustandsbeobachter und ein Kalman Filter (KF) werden implementiert und in Simulationen verglichen. Die Ergebnisse zeigen, dass der vorgeschlagene Ansatz zu guten Ergebnissen f\u00fcr das betrachtete Anwendungsbeispiel f\u00fchrt und Potential f\u00fcr weitere Anwendungsfelder hat.<\/jats:p>","DOI":"10.1515\/auto-2025-0029","type":"journal-article","created":{"date-parts":[[2025,8,6]],"date-time":"2025-08-06T14:00:25Z","timestamp":1754488825000},"page":"558-571","source":"Crossref","is-referenced-by-count":0,"title":["Modellordnungsreduktion f\u00fcr die Zustandssch\u00e4tzung am Beispiel eines Spr\u00fchtrocknungsprozesses"],"prefix":"10.1515","volume":"73","author":[{"given":"Arthur","family":"Lepsien","sequence":"first","affiliation":[{"name":"Fachgebiet f\u00fcr Prozessanalytik, Fakult\u00e4t Naturwissenschaften , Universit\u00e4t Hohenheim , Garbenstra\u00dfe 23, 70599 Stuttgart , Deutschland"},{"name":"Computational Science Hub , Stuttgart , Deutschland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Schaum","sequence":"additional","affiliation":[{"name":"Fachgebiet f\u00fcr Prozessanalytik, Fakult\u00e4t Naturwissenschaften , Universit\u00e4t Hohenheim , Garbenstra\u00dfe 23, 70599 Stuttgart , Deutschland"},{"name":"Computational Science Hub , Stuttgart , Deutschland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2025,8,6]]},"reference":[{"key":"2025091715135944751_j_auto-2025-0029_ref_001","doi-asserted-by":"crossref","unstructured":"J.
