With the wide application of cyber-physical systems(CPS)
it is of vital importance to ensure that the design and implementation of CPS meet critical performance requirements (e.g.
security
reliability).This paper presents a framework for CPS modeling and verification.In the framework
CPS are modelled by HybridUML and then the generic model is transformed to a formal model that is suitable for reasoning with the help of formal methods.The formal method adopted is differential dynamic logic(dL) whose operational model is hybrid program(HP).When transforming a HybridUML model to its corresponding HP presentation
transformation rules are defined according to semantic consistency.After transformation
CPS properties are specified on the basis of the resulting HP
and finally
the properties are automatically verified through the theorem prover KeYmaera.
