Center node: "formal verification of station keeping maneuvers for a planar autonomous hybrid system"
  Abstract: In this case study paper, we investigate the formal verification of a hybrid control law designed to perform a station keeping maneuver for a planar vehicle. Such maneuver requires that the vehicle reaches a neighborhood of its station  in finite time and remains in it while waiting for further commands. We model the dynamics as well as the control law as a      hybrid program and formally verify the reachability and safety properties involved. We highlight in particular the automated    generation of invariant regions which turns out to be crucial in performing such verification. We use the hybrid system theorem prover KeymaeraX to formally check the parts of the proof that can be automatized in the current state of the tool.
