Modeling and Verification of Hybrid Systems Based on Equations
[chapter]
IFIP International Federation for Information Processing
Preserved Fulltext
We describe hybrid observational transition systems, or HOTSs. HOTSs are written in terms of equations and verified by means of equational reasoning. ...
One case study is used to demonstrate how to model hybrid systems as HOTSs, specify HOTSs in CafeOBJ and verify that HOTSs have properties with the CafeOBJ system. ...
Our method proposed in this paper is one of such formal methods. Our method is based on equations and equational reasoning. ...
