Multi-missile distributed cooperative guidance law based on network synchronization principle

According to requirements for multi-missile cooperative attack, a novel distributed cooperative guidance law independent of leader-related information is proposed based on principle of network synchronization. Firstly, problems on multi-missile cooperative attack are converted into the consensus problem of missile-target distance and heading angle by appropriate coordinate transformation based on relative motion equations of missile-targets. Secondly, a multi-missile distributed cooperative guidance law is derived from distributed and consistent strategies. Finally, multi-missile cooperative attack is realized by controlling tangential and normal accelerations based on feedback linearization method. The novelty and advantages of this guidance law is its adaptation to missile with maneuverability and independent of leader's information or target's position. Simulation results show that it is effective for multi-missile cooperative attack with robustness and low communication cost by adopting the guidance law.
