Finite-time adaptive cooperative guidance for multiple missiles

This paper studies the finite-time convergent cooperative guidance problem for multiple missiles to achieve the coordination of the flight time. The control variable is relaxed equivalently and an additional term utilizing the local state information is added such that the finite-time convergence being guaranteed. Furthermore, the time-varying coupling gains are introduced in the guidance law and an algorithm to depict the design process is proposed so that the cooperative guidance law for each follower missile is fully distributed. In addition, finite-time convergence of the guidance error is proved based on Lyapunov theory. Finally, a numerical example is displayed to validate the effectiveness of the proposed theoretical results.
