چکیده

Zusammenfassung Der Beitrag beschreibt den Einsatz der Proper Orthogonal Decomposition (POD) für die Modellreduktion von Partikelprozessen in fluider Strömung. Diese Prozessklasse ist von großer Bedeutung für die chemische und pharmazeutische Industrie. Physikalische Modelle solcher Prozesse sind häufig sehr komplex und für Regelungsaufgaben wenig geeignet. POD bietet hier eine attraktive Möglichkeit, zu reduzierten Prozessmodellen zu gelangen, da das Verfahren sehr flexibel ist, keine spezielle Struktur des Referenzmodells erfordert und interne und externe Koordinaten in einheitlicher Weise behandelt. Der Beitrag stellt das Reduktionsverfahren vor und illustriert es an Beispielen. Summary This paper discusses the application of Proper Orthogonal Decomposition (POD) to the model reduction of particle processes in fluid flow. This class of processes is highly relevant for chemical and pharmaceutical industry. As detailed first principle models of such processes tend to be very complicated, reduced models are required for process control and process design. POD is an attractive method to obtain the reduced models, as it is highly flexible, does not require a special structure of the reference model and treats internal and external coordinates in the same manner. The method is presented and illustrated by examples.

Automatic Model Reduction of Linear Population Balance Models by Proper Orthogonal Decomposition

This paper discusses the use of Proper Orthogonal Decomposition (POD) for the model reduction of particle processes in fluid flow described by Population Balance Equations (PBEs). This class of processes is very important for chemical engineering. As detailed models of such processes turn out to be very complicated, POD is an attractive way to obtain reduced models of low order. This paper repo...

Proper Orthogonal Decomposition for Optimality Systems

Proper orthogonal decomposition (POD) is a powerful technique for model reduction of non–linear systems. It is based on a Galerkin type discretization with basis elements created from the dynamical system itself. In the context of optimal control this approach may suffer from the fact that the basis elements are computed from a reference trajectory containing features which are quite different ...

Rank-1 Incremental Proper Orthogonal Decomposition Based Model Order Reduction for High Dimensional Linear Systems

This work considers a modified incremental proper orthogonal decomposition (iPOD) method and applications to model order reduction (MOR) of linear evolutionary distributed parameter systems. A recursive matrix transformation approach is proposed to obtain reduced order models from high-dimensional systems with less computational cost than the non-recursive case. A detailed analysis of the compu...

Dynamic Simulation and Control of a Continuous Bioreactor Based on Cell Population Balance Model

Saccharomyces cerevisiae (baker’s yeast) can exhibit sustained oscillations during the operation in a continuous bioreactor that adversely affects its stability and productivity. Because of heterogeneous nature of cell populations, the cell population balance equation (PBE) can be used to capture the dynamic behavior of such cultures. In this work, an unstructured-segregated model is used f...
