Embodiment Construction

[0033] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0034] The invention proposes a control method for realizing the assembly of multiple unmanned aerial vehicle mission areas under the condition of distributed communication. This method divides the assembly process into loose formation assembly and tight formation assembly. The loose formation assembly stage completes the traditional assembly task goal, that is, arrives at the designated assembly point at the same time. Aiming at this goal, a loose formation assembly control based on the first-order consensus algorithm is proposed. In the stage of tight formation assembly, the transition from loose formation to tight formation is completed, and the speed and heading angle of each UAV are reached. Aiming at this goal, a tight formation assembly control strategy based on the second-order consensus algorithm is proposed . In addition, on the basis of the design...

Abstract

The invention belongs to the technical field of the multi-unmanned-aerial-vehicle cooperative control, and specifically relates to an aggregated-distributed control method of multi-unmanned-aerial-vehicle task area. The method comprises the following steps: dividing aggregation process into loose formation aggregation and tight formation aggregation, wherein a traditional aggregation task target is accomplished at the loose formation aggregation stage through a loose formation aggregation control strategy based on a first-order consistency algorithm; the transition to the tight formation fromthe loose formation is accomplished at the tight formation aggregation stage through the tight formation aggregation control strategy based on a second-order consistency algorithm. Through the methoddisclosed by the invention, a winding waiting strategy is imported into the first-order consistency algorithm, an aggregation control strategy of a virtual lead plane is imported into the second-orderconsistency algorithm; and the state convergency of the unmanned aerial vehicle formation is realized by controlling the movement of the virtual lead plane, and finally the speeds and course angles of various unmanned aerial vehicles can realize consistency.

Description

technical field [0001] The invention belongs to the technical field of multi-UAV cooperative control, and in particular relates to a multi-UAV mission area assembly distributed control method. Background technique [0002] Due to the limited combat capability of a single UAV, multi-aircraft coordination will become an important combat form of UAVs in the future, and the assembly of mission areas is the basis for realizing multi-aircraft coordinated operations. The existing assembly control methods mainly use the simultaneous arrival at the assembly point as the index, and rarely control the terminal state of the UAVs when they arrive at the assembly point. During the assembly, the states of each UAV are quite different, and the speed and heading angle cannot be converged. Consistent, not conducive to the implementation of subsequent tasks. Contents of the invention [0003] The purpose of the present invention is to provide a multi-UAV mission area assembly distributed co...
