Computing Differential Invariants of Hybrid Systems as Fixedpoints
André Platzer,Edmund M. Clarke +1 more
TL;DR: A fixedpoint algorithm for verifying safety properties of hybrid systems with differential equations whose right-hand sides are polynomials in the state variables is introduced and a saturation procedure that refines the system dynamics successively with differential invariants until safety becomes provable is introduced.
Book ChapterDOI
The image computation problem in hybrid systems model checking
André Platzer,Edmund M. Clarke +1 more
TL;DR: The prerequisites for a safe operation of the roundabout maneuver in air traffic collision avoidance are analyzed and it is proved that purely numerical algorithms can perform continuous image computation with arbitrarily high probability.
Journal ArticleDOI
Supporting Heterogeneity in Cyber-Physical Systems Architectures
Akshay Rajhans,Ajinkya Bhave,Ivan Ruchkin,Bruce H. Krogh,David Garlan,André Platzer,Bradley Schmerl +6 more
TL;DR: This paper proposes a multi-view architecture framework that treats models as views of the underlying system structure and uses structural and semantic mappings to ensure consistency and enable system-level verification in a hierarchical and compositional manner.
Book ChapterDOI
ModelPlex: Verified Runtime Validation of Verified Cyber-Physical System Models
Stefan Mitsch,André Platzer +1 more
TL;DR: ModelPlex is introduced, a method ensuring that verification results about models apply to CPS implementations and a systematic technique to synthesize provably correct monitors automatically from CPS proofs in differential dynamic logic.
Book ChapterDOI
Differential Dynamic Logic for Verifying Parametric Hybrid Systems
TL;DR: A first-order dynamic logic for reasoning about systems with discrete and continuous state transitions is introduced, and a sequent calculus is presented for this logic to prove a parametric inductive safety constraint for speed supervision in a train control system.
