摘要:

针对异构多导弹系统的分布式协同制导问题，在传统比例导引律的基础上设计出一类领航跟随分布式协同制导律。运用代数图论、分布式网络同步原理以及非线性系统一致性理论, 领弹采用基于固定系数的比例导引律，从弹采用基于可变系数的参数自适应比例导引律。该领航跟随分布式自适应协同制导律可使领弹和从弹实现对目标的同时攻击，且各相邻导弹间仅传输各自的可测状态信息，算法具有较低的通信代价和较好的可扩展性。最后给出了相关数值仿真算例，仿真结果验证了控制算法的有效性。

Abstract:

To solve the problem of decentralized cooperative guidance of heterogeneous multiple missiles, a set of distributed leader-follower cooperative guidance law is developed based on the traditional proportional guidance law. On the basis of the algebraic graph theory, the principles of synchronization in distributed networks and the consensus theory of nonlinear systems, the distributive cooperative guidance law of the leader missile is based on the proportional guidance law with fixed navigation coefficient, while the distributive cooperative guidance law of each follower missile is based on the proportional guidance law with adaptive variable navigation coefficient. The synchronized attack on the target could be achieved via the proposed leader-follower cooperative guidance law, which relies on only local interaction with measurable states and exhibits low communication cost as well as good scalability. Finally, nontrivial numerical simulations are performed to verify the effectiveness of the proposed control algorithm
