A European automotive OEM has requested Siemens PLM Software to use its tools and process knowledge to demonstrate the value and need for architecture-driven simulation. Siemens PLM Software proposed a project to demonstrate Simcenter System Synthesis1 as a neutral framework for managing heterogeneous simulations. This includes three major capabilities: ∑ Integration of different subsystem models in the form of Simcenter Amesim2 “supercomponents” and Functional Mock-up Units (FMUs) exported from Dymola3. ∑ Plug-and-play configuration of subsystems regardless of their native software. ∑ Performant execution of heterogeneous simulation architectures with the numerical challenges of segregated strongly coupled systems The focus of the project is on the process of model integration using Functional Mock-up Units (FMUs). An electrical vehicle case-study was selected to illustrate this process.","PeriodicalId":378465,"journal":{"name":"Proceedings of the 2nd Japanese Modelica Conference Tokyo, Japan, May 17-18, 2018","volume":"188 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134399579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dynamics of many physical systems, such as the equations of motion of constrained mechanical multibody systems, are expressed by high-index Differential Algebraic Equations (DAE) so they cannot be simulated directly using standard ODE or DAE solvers. These systems can be converted through index-reduction into ODE or index 1 DAE systems. However FMUs based solely on these latter systems suffer from drift in hidden constraints on the states. As a consequence, the simulation may results in physically meaningless solutions. In this paper, we propose an extension of the FMI standard to handle DAE Systems of index 1 or higher and ODE with constraints. This FMI extension requires only few additions to the FMI specification, all of which can be omitted for FMUs that represent ODE systems or FMUs that do not support DAE handling. The extension has been implemented in solidThinking ActivateTM and two examples that illustrate the ease of implementation and the effectiveness of the method will be discussed.","PeriodicalId":378465,"journal":{"name":"Proceedings of the 2nd Japanese Modelica Conference Tokyo, Japan, May 17-18, 2018","volume":"73 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133686323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We address this problem via a system architecture that combines theradiant heating system with a separate air-source heat pump serving the same space. In this paper, we develop a new coordinating control method for this proposed system by using a set of reduced order models generated from a set of coupled Modelica models of the individual subsystems. This new control architecture does not require significant modification of standard heat pump control architectures, and results in both improved thermal comfort and reduced energy consumption.

The effect of the addition of auxiliary load on vehicle range is also explored based on these two countries in conjunction with corresponding drive cycles.

However, the number of states within a MODELICA-based multibody model has to remain constant during a simulation. Therefore, the variable structure of launch vehicle models is often considered by using time- and state-dependent conditional statements and separation components. Such an approach can lead to a higher number of equations in the model and to a higher model complexity, respectively. In this paper, a mission-dependent sequential simulation approach for the modeling and trajectory visualization of launch vehicle systems is introduced. Here, the system is divided into characteristic phases, which are modeled with the DLR LauncherApplications Library capitalizing its modular, reusable and user-friendly structure to maintain compatibility between phases and to decrease the overall model complexity and the number of equations.","PeriodicalId":378465,"journal":{"name":"Proceedings of the 2nd Japanese Modelica Conference Tokyo, Japan, May 17-18, 2018","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124557962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
