Simulation physiologischer Regelkreise mit der objektorientierten Modellbibliothek “HumanLib”

Abstract: Zusammenfassung Die “HumanLib” ist eine objektorientiert aufgebaute Modellbibliothek bestehend aus Komponenten des Herz-Kreislauf-Systems sowie körpereigenen Regelkreisen. Im Beitrag werden Aufbau und Modellierungsmethodik beschrieben. Anhand zweier Testszenarien werden Simulationsdaten mit Messdaten aus einem in vivo Versuch am Kalb sowie physiologischen Normalwerten verglichen. Abstract “HumanLib” is an object-oriented model library with components of the human cardiovascular system and physiological control mechanisms. In this paper, after specifying structure and modeling methods, simulated data is compared to measured data of an experimental calf model and to physiological textbook data.

Parametric Model Order Reduction by Matrix Interpolation

Abstract: In this paper, a new framework for model order reduction of LTI parametric systems is introduced. After generating and reducing several local original models in the parameter space, a parametric reduced-order model is calculated by interpolating the system matrices of the local reduced models. The main task is to find compatible system representations with optimal interpolation properties. Two approaches for this purpose are presented together with several numerical simulations.

An architecture of an Intelligent Digital Twin in a Cyber-Physical Production System

Abstract: Abstract The role of a Digital Twin is increasingly discussed within the context of Cyber-Physical Production Systems. Accordingly, various architectures for the realization of Digital Twin use cases are conceptualized. There lacks, however, a clear, encompassing architecture covering necessary components of a Digital Twin to realize various use cases in an intelligent automation system. In this contribution, the added value of a Digital Twin in an intelligent automation system is highlighted and various existing definitions and architectures of the Digital Twin are discussed. Flowingly, an architecture for a Digital Twin and an architecture for an Intelligent Digital Twin and their required components are proposed, with which use cases such as plug and produce, self-x and predictive maintenance are enabled. In the opinion of the authors, a Digital Twin requires three main characteristics: synchronization with the real asset, active data acquisition from the real environment and the ability of simulation. In addition to all the characteristics of a Digital Twin, an Intelligent Digital Twin must also include the characteristics of Artificial Intelligence. The Intelligent Digital Twin can be used for the realization of the autonomous Cyber-Physical Production Systems. In order to realize the proposed architecture for a Digital Twin, several methods, namely the Anchor-Point-Method, a method for heterogeneous data acquisition and data integration as well as an agent-based method for the development of a co-simulation between Digital Twins were implemented and evaluated.
