Modeling and simulation of CPS based on SysML and modelica(KG)

Abstract

Cyber-Physical Systems (CPS) is usually associated with large numbers of domains. The domain relevance allows system engineers' knowledge to spread many domains. The efficiency and accuracy of modeling are not able to be guaranteed. Therefore, in this paper, a set of CPS modeling guideline is proposed based on SysML, and the system's 4-layer abstract hierarchy and the kind of modeling products obtained on each layer are defined. Based on this, a modeling specification containing seven sub-processes is designed. In order to verify the correctness of CPS function and the consistency of the business logic at the primary phase of the design, we summarize the mapping rules of SysML-Modelica and define the algorithm of model conversion. Finally, a simple CPS case is used to verify our task. The results show that this method can be effective in CPS's modeling and Simulation.
