Abstract:

Cooperative control strategy can support coordinated attack for multi-UAV in threat environment, and achieve the greatest combat effectiveness with time constraint. It is a crucial problem with significant theoretical value and great practical value. Firstly, a cooperative path planning based expanded Voronoi diagram was proposed. The threat environments considered different types of threats and no-fly zones with different threat distances. Line-of-sight of path shortening algorithm and smoothing algorithm were proposed to realize dynamic optimization of the paths. Secondly, time error signal was obtained from real time-to-go and the estimated time-to-go by adopting a simple online time-to-go estimation method. Dynamic path planning on the basis of the estimated path was done to satisfy the impact time constraint. At last, simulation results proved validity and real-time. This method can support cooperative attack for multi-UAV.

I. Introduction

Modern information wars emphasize system resistance and cooperative attack. The possibility of single-UAV attack becomes less, while coordinated attack for multi - UAV is a more modern ideas of information warfare methods of warfare [1], [2]. But effective collaborative control strategies for supporting multiple UAVs under threat environment and meet time constraints with the greatest probability of success, and the lowest risk of hitting the target, at minimal cost, minimal casualties for maximum operational efficiency, is a theoretical and practical issues of significance, as well as hotspots of aircraft control technology.
