摘要
The Cyber-Physical System has been characterized by deep integration of computing process and physical process, heterogeneous composition, etc. So it is difficult to model Cyber-Physical System and to analyze its properties. An approach to model Cyber-Physical System and to analyze its safety based on multiple modeling languages transformation is put forward. We model the Cyber-Physical System by Hybrid System Description Language, and analyze its safety by Hybrid Program Language. The meta-model of Hybrid Program is established. The rules that automatically transform Hybrid System Description Language meta-model to Hybrid Program meta-model are provided. Result shows that this method can model Cyber-Physical System intuitively, meanwhile analyze its safety avoiding state space explosion in formal validation.
