Abstract:

To address the problem of multi-vehicle cooperative strike against maneuvering targets, a cooperative guidance method considering impact time control and terminal area sealing was proposed. The distributed disturbance observer was utilized to estimate target maneuvers. Based on the consensus errors of the impact time, the cooperative guidance law in the line-of-sight direction was proposed to achieve simultaneous hits on targets at a specified time. By considering the motion states of targets, the instructions of the terminal area sealing were designed to construct the sliding mode surface and design the line-of-sight guidance law, so as to ensure the convergence of the sliding mode and the angles of line-of-sight. Theoretical analysis has indicated that the designed guidance method can achieve the area sealing of targets with impact time control. The effectiveness of the proposed method is verified through numerical simulations.
