This paper presents a distributed time and space cooperative guidance law based on a higher-order sliding mode protocol for the consensus among multiple missiles in the Line of Sight (LOS) and perpendicular to the LOS direction using a Multi-Agent System (MAS) approach. A graph theory is used to represent the communication between the missiles and a leader-follower approach of MAS is used to design the super-twisting sliding mode protocol for the consensus. The cooperative guidance law not only ensures robustness but also reduces the convergence time and the chattering during the consensus among multiple missiles. The stability condition of the consensus is also derived using the Lyapunov function.The protocol is validated among 4 missiles in the given pattern with two scenarios (1) Missile launching with different velocities and (2) Missile launching with the same velocities. The simulation results show that the consensus is achieved in a finite time. Further to show the efficacy of the robust cooperative guidance law, the results are compared with the guidance law designed using classical sliding mode control protocol with constant-rate and constant propositional rate reaching law. From the comparative analysis, it is inferred that the distributed time and space cooperative guidance law based on a higher-order sliding mode protocol performs better in terms of time required for consensus, time to hit the target, and precision.

“…(2) Unlike the guidance laws presented in [2,[13][14][15][21][22][23], which only investigate the simultaneous arrival problem of multiple missiles, this study provides a strategy that can guarantee that all group members arrive at the target at the same time by imposing the preassigned impact angles. As a result, the mission effectiveness can be greatly increased [24].…”

The problem of the distributed cooperative guidance law of multiple missiles attacking a stationary target with impact angle constraint is investigated. A distributed cooperative guidance law, which consists of a nonsingular terminal sliding mode component for ensuring finite time convergence to the desired LOS angle and a coordination component for realizing finite time consensus of time-to-go estimates, is proposed. Analysis shows that the guidance law designed in this study can ensure that missiles’ time-to-go estimates represent real times to go once all the missiles fly along the desired LOS. Therefore, simultaneous arrival can be guaranteed. Furthermore, it is modified to accommodate the communication failure cases. Compared with existing results, this guidance law owns faster convergence rate and can satisfy large impact angles. Numerical simulations are performed to demonstrate the effectiveness of the proposed guidance law.

In this paper, a novel three‐dimensional fixed‐time integrated guidance and control (IGC) scheme with multi‐stage interconnected observers is proposed for cooperative attacks using multiple missiles against a maneuvering target under impact angle and input saturation constraints. External disturbances, modeling errors, and aerodynamic parameter variations are considered as system uncertainties and a three‐channel fully coupled IGC model for multiple missiles is established. The IGC system is designed optimally based on fixed‐time stability theory, sliding mode control, and the backstepping technique. Three inter‐cascaded fixed‐time disturbance observers based on an improved super‐twisting algorithm are designed to estimate and compensate for system uncertainties. Second‐order command filters are used to constrain virtual control signals, and additional filtering error subsystems are introduced to compensate for the tracking errors of filters. System stability and uniformly ultimately fixed‐time boundedness of all states are proven using the Lyapunov stability theory. Finally, the limits of the acceleration components of the maneuvering target perpendicular to the line of sight direction are derived. The effectiveness of the designed IGC scheme and the ability of multi‐stage interconnected observers to sense disturbances with each other are verified through simulations.
