Multiple Tactical Missiles Cooperative Attack with Formation-Containment Tracking Requirement along the Planned Trajectory

This paper studies the cooperative guidance and control problems with formation-containment tracking requirement under directed topologies for multiple tactical missiles. The states of the formation-leaders can not only keep a parallel triangle formation but also make tracks for the state trajectory generated by the tracking-leader, while the states of followers converge to the convex hull formed by those of the formation-leaders. Firstly, an integrated cooperative guidance and control framework is proposed, and combat missions are distinguished in line with tactical missiles rewarded different functions in practical applications. Then, a terminal slide mode guidance law with impact angle is presented in three-dimensional space, which ensures attack missile to attack the target in finite time. Sufficient conditions for multiple tactical missiles to achieve formation-containment tracking are derived. On the basis of Lyapunov theory, it is shown that the expected formation-containment tracking can be realized by reconnaissance and decoy missiles in the presence of the tracking-leaders' unknown control input. In addition, in the case of unknown drag force, the six degrees of freedom missile controller is designed by combining genetic algorithm and disturbance observer to dynamically adjust the rudder deflection and thrust, ensuring stable tracking of overload command during cooperative attack. Finally, numerical simulations validate the feasibility and effectiveness of the proposed results.
