带视线角约束的三维超螺旋滑模协同制导律

In view of the problem of three-dimensional multi-missile cooperative guidance with line-of-sight angle constraint, a three-dimensional multi-missile cooperative guidance law is proposed based on second-order consensus theory and adaptive super-twisting sliding mode control method. In the line-of-sight direction, the relative distance and relative velocity of the missile will converge to consensus in finite time. In the elevation direction and azimuth direction of line-of-sight, this paper proves that the missile can achieve the desire line-of-sight angle and the line-of-sight angle rate converges to zero in finite time. The adaptive super-twisting sliding mode control method adopted can effectively solve the chattering problem of traditional sliding mode and be robust to maneuvering targets. Finally, the effectiveness of the designed cooperative guidance law is demonstrated in the simulation experiment through the comparative analysis.
