分布式通信模式下的多导弹协同制导与控制律

A cooperative guidance and control law was proposed concerning multiple slide-to-turn missiles with decentralized communication attacking the target based on the leader-follower mode. The leader was supposed to attack the target according to proportional navigation guidance law. The reasonable communication topology was set and the leader was set to be the root of the topology, and then the range-to-go of each missile was regarded as a cooperative variable, the consensus cooperative strategy was discussed under the fixed communication topology and changing communication topology, which made the range-to-go of followers consensus with that of the leader. Then the expected range-to-go of followers was obtained from the consensus cooperative strategy. Based on feedback linearization theory and the constraint of missile's gimbal angle, the command of velocity lead angle of missile was deduced to make the follower's actual range-to-go track the expected range-to-go. Considering missile's guidance and control together, the integrated guidance and control model of follower in horizontal plane was established, a robust controller was designed based on the sliding mode dynamic surface theory to track the command of velocity lead angle with high precision. Simulation results proved the validity of the cooperative guidance and control law.
