Model-Based Integration Platform for FMI Co-Simulation and Heterogeneous Simulations of Cyber-Physical Systems

Abstract

Virtual evaluation of complex Cyber-Physical Systems (CPS) [1] with a number of tightly integrated domains such as physical, mechanical, electrical, thermal, cyber, etc. demand the use of heterogeneous simulation environments. Our previous effort with C2 Wind Tunnel (C2WT) [2] [3] attempted to solve the challenges of evaluating these complex systems as-a-whole, by integrating multiple simulation platforms with varying semantics and integrating and managing different simulation models and their interactions. Recently, a great interest has developed to use Functional Mockup Interface (FMI) [4] for a variety of dynamics simulation packages, particularly in the automotive industry. Leveraging the C2WT effort on effective integration of different simulation engines with different Models of Computation (MoCs), we propose, in this paper, to use the proven methods of High-Level Architecture (HLA)-based model and system integration. We identify the challenges of integrating Functional Mockup Unit for Co-Simulation (FMU-CS) in general and via HLA [5] and present a novel model-based approach to rapidly synthesize an effective integration. The approach presented provides a unique opportunity to integrate readily available FMU-CS components with various specialized simulation packages to rapidly synthesize HLA-based integrated simulations for the overall composed Cyber-Physical Systems.

A Software Architecture for Simulation and Visualisation based on the Functional Mock-up Interface and Web Technologies

“…After the introduction of FMI, several authors have shown how to use it in modular simulations. A recent example is Neema et al (2014), who used FMI for component models which where integrated using HighLevel Architecture (HLA). Their system supports component models from a range of different modelling tools, in addition to FMI support.…”

Open Standards Simulation Flow for Heterogeneous System Models1

“…A promising approach was suggested by Ptolemy II project [10] with a rigorous actor-based framework for handling heterogeneity of models by hierarchical composition of different MoCCs (Models of Computation and Communications) [11]. Another research direction is focused onintegration of Simulink, Modelica and other modeling tools with Systems Seattle, July [13][14][15][16]2015 Engineering languages like SysML. Authors of [12] developed a UML profile and a complementary software that enables referencing Simulink models from SysML model.…”

A simulation framework for industrial wireless networks and process control systems

“…Simulations are also widely used to evaluate complex systems, such as cyber-physical systems, by cosimulating behaviors of component systems/networks in a hierarchical High-Level Architecture (HLA) [25], [26]. Eventdriven simulators, such as NS2/NS3, OPNET and OMNET++, are developed for such purposes [28], [27].…”
