Petri Net Based Modeling Approach for Fault Affected UAV Subsystems Reconfiguration

Military planners and tacticians anticipate that future battles will likely take place in more urban settings with path obstacles and hostile agents. Many of these combat and emergency response situations will prefer autonomous UAVs (Unmanned Air Vehicles) to manned vehicles for providing situation awareness for command and control (C2) as well as carrying out certain mission scenarios. One of these scenarios is to employ a team of UAVs to complete a more sophisticated mission than what each UAV is capable of achieving. These autonomous vehicles will be exposed to internal and external threats, such as system faults/failures and battle damages, hence they will be required to operate with the ability of being reconfigured in real-time. These requirements pose stringent challenges to the command and control of an UAV.
