Aircraft safety interval regulation and control method for autonomous operation route

Abstract

The invention discloses an aircraft safety interval regulation and control method for an autonomous operation route, and the method comprises the steps: modeling an air traffic operation system as a multi-agent system, describing a system communication interaction relation as a time-varying directed graph, and carrying out the control of the safety interval of an aircraft on the basis of a leader-following control thought of a heterogeneous aircraft system of swarm intelligence. Identifying a leader aircraft in the system and determining a corresponding aircraft adjacency relationship; a group consistency control law under the asymmetric communication time-varying topology is designed, while an inter-aircraft local information interaction mechanism is met, aircraft safety interval keeping and speed and direction angle consistency in a system are realized, and the conflict risk caused by interval loss in a cluster is reduced; and an obstacle avoidance target outside the system is further considered, a designed distributed control algorithm is improved, collision with other running targets in the air is avoided, and orderliness and safety of aircraft cluster running are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of air traffic management, and in particular relates to an aircraft safety interval control method for an autonomously operated air route. Background technique [0002] In recent years, with the rapid development of the global economy, the demand for air transport market is increasing day by day. The existing centralized separation control method centered on ground controllers has problems such as heavy control workload, lagging maneuver response, and limited aircraft flight flexibility, which cannot meet the needs of safe and efficient operation in complex airspace environments. In order to further enhance the support capability of the air traffic control system, the "2019 Strategic Implementation Plan" issued by NASA and the "2020 Artificial Intelligence Roadmap" issued by the European Aviation Safety Agency successively proposed the concept of autonomous operation of air traffic, the core of which is By ...

AI Technical Summary

Problems solved by technology

[0003] However, in the scenario of autonomous operation, the flight route selection of aircraft is more flexible, and the flight situation is more complex. The traditional separation control method is no longer applicable, and it is difficult to maintain efficient and safe operation requirements in the airspace.

In addition, under the condition of high-density aircraft operation, the cascading effect of separation control is significant, and secondary conflicts occur frequently.
