摘　　要：在目标-攻击弹-防御弹群(target-attacker-defenders,TADs)系统中,防御弹群通过与目标(载机)异构协同、弹群间同构协同以保护载机并降低单弹脱靶的风险。针对TADs系统在二维平面下的协同主动防御模型进行了研究,采用机/弹协同和防御弹群协同的两层制导策略。在机弹协同方面,防御弹领弹与载机进行异构协同,考虑载机及防御弹领弹的机动能力限制,采用协同视线制导律(cooperative line of sight guidance,CLOSG)分别得到载机和防御弹领弹的制导指令;在防御弹群协同方面,考虑单弹计算能力约束,拦截时间约束和加速度约束,设计出基于分布式模型预测控制(distributed model predictive control,DMPC)的算法实现弹群从弹和防御弹领弹协同同时抵达并拦截攻击弹。仿真结果表明,多防御弹协同一致拦截制导算法能够实现TADs系统中载机和防御弹群的异构协同主动防御,并实现防御弹群的一致性同时拦截,以降低单弹脱靶的风险。In the target-attacker-defenders(TADs)system,the defenders protect the target(aircraft)and reduces the risk of failed interception with a single defender by heterogeneous synergy between the defenders and the target as well as the homogeneous synergy among the defenders.The cooperative active defense model of TADs system in the planar scenario is studied,and a two-layer guidance strategy of target-defender’s synergy and defenders group’s synergy is adopted.In terms of target-defender’s synergy,the leading defender and the target aircraft carry out heterogeneous synergy,considering the maneuverability constraints of the target aircraft and the leading defender,using the cooperative line of sight guidance(CLOSG)law to obtain the guidance commands for the target aircraft and the leading defender respectively;in terms of the defenders group’s synergy,a distributed model predictive control(DMPC)based algorithm is designed to achieve simultaneous arrival and interception for the attacker by the following defenders group and the leading defender,considering the single defender’s computational capability constraint,interception time constraint and acceleration constraint.Simulation results show that the multi-defenders cooperative and simultaneous interception guidance algorithm can realize the heterogeneous cooperative active defense for target and defenders’group in the TADs system,and realize the simultaneous interception for the defenders to reduce the risk of failed interception with a single defender.
