Cooperative Salvo Attack Guidance Law Based on Predefined-Time Convergent Error Dynamics

This paper aims at developing a cooperative salvo attack guidance law for multiple missiles based on real-time communication. The infinite-time-convergent characteristic aggravates the difficulty of control parameters tuning. Herein, a cooperative salvo attack guidance law based on predefined-time convergent control law without parameter tuning is presented, and the predefined-time convergence of cooperative error is proven by the second method of Lyapunov. Comparative simulations are conducted to demonstrate the effectiveness and advantage of the proposed predefined-time cooperative salvo attack guidance law over existing fixed-time cooperative salvo attack guidance law.
