Embodiment 1

[0121] The simulation experiment is set as follows: three aircraft form a cooperative guidance system, one of which is the pilot aircraft, and two of them are follower aircraft. Fly horizontally in the negative direction of the x-axis, the initial velocity of the pilot aircraft is 200m / s, and the initial line-of-sight angle is 45°. The initial position of the leading aircraft is 0, the value of the position vector L between the predetermined position of the following aircraft and the leading aircraft is 100m,

[0122] During the flight, the distance between the following aircraft and the leading aircraft is always 100±10m, and the positional relationship between the aircraft at the guidance terminal and the target is:

Abstract

The invention discloses a cooperative guidance method and system based on a leader and follower principle. A piloting aircraft and a following aircraft are arranged, the piloting aircraft carries out guidance, the following aircraft follows the piloting aircraft to achieve cooperative guidance, and the piloting aircraft obtains guidance parameters by constructing a neural network in the guidance process. The cooperative guidance method and system based on the leader and follower principle have the advantages that the control process of the multiple aircrafts during guidance is simplified, the flight path is stable and efficient in the guidance process, and the system stability is good.

Description

technical field [0001] The invention relates to a guidance method, in particular to a cooperative guidance method based on the leader-follower principle, which belongs to the field of unmanned aerial vehicle control. Background technique [0002] Nowadays, unmanned aerial vehicles have been widely used in engineering practice. During the cluster flight of the aircraft, it needs to be controlled cooperatively. [0003] However, when multiple aircraft form an aircraft group for long-distance flight (intermediate guidance), due to the need for simultaneous control of guidance, attitude, and aircraft coordination, the amount of calculation will increase significantly, which requires a relatively simple and efficient coordination Guidance method is used to guide multi-vehicles for long-distance formation flight. [0004] In addition, sometimes the target that the aircraft group needs to approach is in a moving state, and the established guidance law will not allow the aircraft ...
