Modeling and Safety Analysis of Autonomous Underwater Vehicles Behaviors

Testing underwater vehicles in operational conditions is expensive. Formal models can lower the cost of operational testing and validation for these systems, as they allow detecting problems earlier. We propose modeling the underwater vehicle’s behavior as Timed Automata, and discuss examples of property patterns which can be handled by observer Timed Automata and Timed CTL properties. The goal is to build a set of specifications which can then be used for testing and validation of controllers in underwater vehicles.
