| Summary: | Multi-missile cooperative guidance is an important way to improve the strike effect of missiles, and the fast convergence of guidance commands can effectively ensure the stability of multi-missile systems. The cooperative guidance method based on the fixed-time consistency theory has been proved to be suitable for multi-missile coordinated attack, but the non-singularity problem of the controller itself will have a large impact on the striking effect of the multi-missile system, so this paper designs a fixed-time fast non-singular distributed cooperative guidance law to solve the above problem. First, a fixed-time cooperative guidance law with fast convergence is designed in the line-of-sight (LOS) direction and an auxiliary function is designed to solve the singularity problem; after that, a cooperative guidance law in the LOS normal direction is designed to ensure that each missile attacks the target simultaneously at the desired attack angle. Finally, the effectiveness, superiority and robustness of the designed guidance law are demonstrated by numerical simulations. |
