If the property is not satisfied by the abstraction, the verification is inconclusive and the abstraction needs to be refined so that a less conservative model can be checked. If the hybrid system does not satisfy the property, this verify-refine procedure usually will not terminate. This paper introduces the concept of strong negation for ACTL formulas as an auxiliary condition that can be verified to obtain a conclusive negative verification result from a finite-state abstraction in certain cases. The concepts are illustrated with an example from automotive powertrain control. 收起
