Next Generation Architecture for Air Traffic Management Systems

摘要

The study of hierarchical, hybrid control systems in the framework of air trafficmanagement systems (ATMS) is presented. The need for a new ATMS arises from the overcrowding of large urban airports and the need to more efficiently handle larger numbers of aircraft, without building new runways. Recent technological advances, such as the availability of relatively inexpensive and fast real time computers both on board the aircraft and in the control tower, make a more advanced air traffic control system a reality. The usefulness of these technological advances is limited by today's Air Traffic control (ATC), a ground-based system which routes aircraft along predefined jet ways in the sky, allowing the aircraft very little autonomy in choosing their own routes. In this paper, we propose an architecture for an automated ATMS, in which much of the current ATC functionality is moved on board each aircraft so that the aircraft may calculate their own deviations from predefined trajectories without consulting ATC. Within the framework of this architecture, we describe our work in on-board conflict resolution strategies between aircraft, and in deriving the flight mode switching logic in the flight vehicle management systems of each aircraft.
