Problems solved by technology

[0004] However, the above literatures mainly solve the coordination problem at the trajectory level, such as coordinating the arrival time of multiple UAVs as a whole, or coordinating multiple UAVs to reach the same target, but they do not consider the coordination problem at the trajectory level

Abstract

The invention discloses a multiUAV cooperative trajectory planning method and system, equipment and a storage medium, and the method comprises the steps: firstly building a constraint model and an objective function of cooperative trajectory optimization, describing a cooperative trajectory planning problem as a parameter optimization problem, then employing B spline curve parameterization to represent UAV trajectories in combination with an aircraft performance model, and finally, solving a parameter optimization problem by adopting an evolution method to obtain a coordination trajectory meeting a space coordination requirement and a time coordination requirement to realize space-time coordination among multiple UAV trajectories.

Description

technical field [0001] The present invention relates to the technical field of UAV control, in particular, to a multi-UAV collaborative trajectory planning method, system, device, and computer-readable storage medium. Background technique [0002] When multiple unmanned aerial vehicles (UAVs) cooperate to carry out ground strike missions, in order to improve combat efficiency and achieve predetermined effects, it is often necessary to plan the combat process of multiple UAVs and generate detailed cooperative combat plans. Among them, collaborative trajectory planning is the key process of multi-UAV collaborative planning. In the ground attack phase, in order to maximize the probability of successfully completing the mission, all UAVs are required to start from the same or different starting points at the same time, and arrive at a specific attack position at the same time or in a certain time sequence to perform the mission, so that even if some UAVs are damaged , other UAV...
