摘要

The research investigates the multi-constraint guidance challenge for multiple missiles in three-dimensional (3D) directed communication topology, presenting an adaptive cooperative guidance algorithm. First, along the line-of-sight (LOS) direction, a novel radial velocity consensus protocol is devised to allow missiles to accomplish simultaneous interception of the target at a specified radial velocity under directed communication topology. Second, in the normal direction of LOS, a novel robust adaptive non-singular predefined-time sliding mode guidance law is developed by integrating adaptive control and sliding mode control. By utilizing a parameter adaptive controller to estimate the upper bound of external disturbances, the algorithm guarantees that missiles intercept targets with diverse terminal angles within a predefined time, while effectively mitigating chattering and avoiding singularity issues. Simulation results demonstrate the superiority and robustness of the proposed guidance law.
