A Fast Track Planning Method for Intelligent Aircraft under Multiple Constraints

Abstract

The invention discloses a method for quickly planning the track of an intelligent aircraft under multi-constraint conditions, belonging to the technical field of aircraft path planning, comprising the following steps: comprehensively analyzing the characteristics of the aircraft track planning, establishing a mathematical optimization model of multi-objective and multi-constraint conditions; obtaining an example Information; use the heuristic neighborhood search algorithm to solve the example, obtain a variety of feasible path schemes and characterize them, the present invention aims at the problem of rapid planning of the effective flight path of the aircraft in different actual flight environments, and establishes to minimize the path and the minimum The number of corrections is an objective function, including path balance constraints, path uniqueness constraints, traversal path loop constraints and other multi-objective multi-constraint mathematical optimization models. At the same time, a heuristic neighborhood search algorithm is proposed, which combines simulated annealing to find local The optimal node is used as the next traversal node of the aircraft, and the corresponding search step size is specified, so as to improve the convergence performance of the algorithm, and a better track route can be quickly obtained through the present invention.

Description

technical field [0001] The invention belongs to the field of aircraft track planning and control, and in particular relates to a rapid planning method for an intelligent aircraft track under multi-constraint conditions. Background technique [0002] Since the British invented the first aircraft (Aerial Vehicle) in 1917, aircraft technology has become a very important development project in the military and civilian fields. In the military field, aircraft can perfectly complete many military tasks including reconnaissance of terrain and enemies and ground attack. In the civilian field, aircraft also play a huge role in surveying and mapping, resource exploration and aerial photography. With the rapid development of computers, information and science and technology, the performance, results and manipulation of aircraft have become more and more complex. Aircraft trajectory planning is a key technology to realize autonomous navigation of aircraft, and it is of great significa...
