Mid and short term conflict resolution in autonomous aircraft operations

We investigate the conflict resolution problem in a self separation airspace. Using the recent advances in the fields of robotics and control, we use navigation functions to resolve conflicts arising in the Short Term, which guarantee conflict avoidance, while in Mid Term, a model predictive controller makes sure that the designed system respects the operational constraints of the situation and maximizes some performance for the system. Both algorithms operate in a decentralized scheme, following the autonomous aircraft concept investigated under the European project iFly. Priority issues are discussed and ways to take them into consideration in our setting are shown. The algorithm performance is demonstrated on simulations in planar configurations.
