Cooperative Impact-time-control Guidance of Multiple Flight Vehicles with Uncontrollable Velocity

Abstract

Time-cooperative guidance of multiple flight vehicles can not only improve the accuracy of the guidance level, but also greatly improve the penetration capability. In this paper, a cooperative impact-time-control guidance law of multiple flight vehicles with uncontrollable velocity to realize simultaneous arrival is proposed. Firstly, the multi-agent consensus algorithm is introduced as basic theory. Secondly, a structure combined individual impact-time-control guidance with the cooperative control protocol is proposed, in which the coordination module is to generate coordination instructions, and local impact-time-control guidance law is adopted to execute instruction. Further, the finite-time time-cooperative guidance of multiple flight vehicles is studied to achieve the convergence of time-to-go instructions in finite time. Finally, the effectiveness of the above cooperative guidance law with uncontrollable velocity is verified by simulation.
