Adaptive multi-missile cooperative guidance law based on integral sliding mode

This paper addresses the problem of cooperative multi-missile interception of maneuvering targets with terminal angle-of-attack constraint. Firstly, a cooperative guidance model of multi-missile with terminal angle of attack constraint in two-dimensional plane is given. Based on the multi-intelligence finite-time consistency theory, integral sliding mode theory and adaptive algorithm, cooperative guidance laws along the line of sight direction and line of sight normal upward are designed to ensure that each missile can hit the target at the desired angle simultaneously. Finally, the stability analysis of the designed cooperative guidance law is carried out with the help of Lyapunov stability theory, and the effectiveness of the designed cooperative guidance strategy is verified by numerical simulation.
