    摘要: Methods and apparatus are provided for controlling an unmanned air vehicle (UAV) that includes a plurality of independently controllable control vanes. Control vane position commands are supplied that will move each of the control vanes to a position that will cause the UAV to implement a commanded maneuver. Inoperability of one of the control vanes is sensed, and the position of the inoperable control vane is determined New control vane position commands are determined, based on the determined position of the inoperable control vane, which will also cause the UAV to implement the commanded maneuver.

    摘要: A position keeping system, useable to maintain a position of a vehicle in a vehicle formation, to keep all formation members flying at a specified velocity and altitude, and to perform commanded maneuvers, determines guidance corrections based on a track state referenced to a leader or a virtual leader of the formation and on a formation position error indicating the error in the position of the vehicle in the formation. The guidance corrections are required so as to maintain the vehicles in the formation.

    摘要: Collision avoidance systems and methods are implemented on unmanned mobile vehicles to supplement map-based trajectories generated by the vehicles' navigation systems. These systems include radar, which detect obstacles in the path of the unmanned mobile vehicles, and collision avoidance modules, which enable the vehicles to avoid unexpected obstacles by adjusting their trajectories and velocities based on feedback received from the radar. In general, when an obstacle is detected by the radar, the collision avoidance module modifies the commanded velocity of an unmanned mobile vehicle by subtracting from the nominal commanded velocity the component that is in the direction of the obstacle. The magnitude of the velocity modification typically increases as the distance between the mobile vehicle and the obstacle decreases.
