A multi-UAV sequence flight control method

Abstract

The invention discloses a method for sequence flight control of multiple unmanned aerial vehicles. The method includes that a 4D flight path, including space coordinates and time coordinates, of eachunmanned aerial vehicle is pre-generated according to an unmanned aerial vehicle sequence flight scheme and inputted into a flight control system of each unmanned aerial vehicle; in sequence flight, an active control and passive control combined control method is adopted; under normal communication conditions, each unmanned aerial vehicle flies according to waypoint information sent in real time by a ground station to each unmanned aerial vehicle, so that active control in sequence flight control of the multiple unmanned aerial vehicles is realized; under abnormal communication conditions, each unmanned aerial vehicle is controlled by the corresponding flight control system according to the corresponding pre-inputted 4D flight path, so that passive control in sequence flight control of themultiple unmanned aerial vehicles is realized until communication conditions return to normal. Compared with the prior art, the method has advantages of high safety and control flexibility.

Description

technical field [0001] The invention relates to a multi-UAV sequence flight control method, which belongs to the technical field of multi-UAV sequence flight control. Background technique [0002] In recent years, with the rapid development of artificial intelligence, the field of UAV (Unmanned Aerial Vehicle) control technology has also advanced by leaps and bounds, and related technologies have become more and more mature. What attracts people's attention is the commercial performance of UAV sequence flight. UAV sequence flight refers to pre-designing a multi-UAV combination formation array or pattern, and then sequentially importing the position waypoints of each UAV corresponding to each formation or pattern into the UAV flight control system , and finally each UAV will fly to the designated waypoint according to the flight instructions to complete the arrangement and transformation of the formation. [0003] At present, UAV sequence flight performances mainly include U...

Problems solved by technology

In this process, there will be many problems that cannot be solved by the current technology. For example, the current multi-UAV sequence flight waypoints are dense, resulting in a large amount of calculation and high complexity. At present, there is no special UAV trajectory planning. software; and communication is easily interrupted, causing the ground station to fail to send commands, all drones will lose control, and the risk is unpredictable, etc.
