Embodiment Construction

[0066] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0067] An event-triggered differential game cooperative guidance method disclosed in the present invention includes a set of nodes Strongly connected directed communication topology diagram between composed multi-agent systems Among them, the edge set Indicates the information transmission channel between agents, if (i,j)∈ε, it means that agent i can receive the information of agent j, and vice versa. For agent i, the set of all agents that can receive information is used express. representation diagram The adjacency matrix of , such as there is a communication link between agent i and agent j, that is, when (i,j)∈ε, the matrix element a ij = 1, otherwise a ij =0. Here we assume the graph There is always a directed path between any two nodes in the graph and And there is no self-loop, that is, a ii =0. picture The in-degree mat...

Abstract

The invention discloses a differential game collaborative guidance method based on event triggering, and belongs to the technical field of aircraft guidance. According to the method, based on a differential game theory and a topological structure, a multi-missile cooperative guidance system is modeled into a nonlinear zero-sum differential game system; an event triggering mechanism is introduced, and communication transmission of redundant signals among the missiles is avoided; and an approximate solution of the nonlinear coupling HJI equation set is obtained by using a self-adaptive dynamic programming technology. The optimal controller triggered by the event is updated online in real time, multiple missiles can hit the same target at the same collision angle within the required time, and meanwhile, communication resources and calculation cost between the missiles can be effectively reduced.

Description

technical field [0001] The invention relates to an event-triggered differential countermeasure cooperative guidance method, which belongs to the technical field of aircraft guidance. Background technique [0002] In the increasingly fierce arms race of various countries, missiles have become a research hotspot of military weapons due to their advantages such as long range, high precision, high power and strong penetration ability. However, with the increasingly complex combat environment and the increasingly intelligent interception targets, the interception accuracy and interception success rate of the widely used traditional guidance laws have been greatly reduced. As an effective tool for solving conflict confrontation or competition problems, differential games can be modeled and analyzed according to specific confrontation or conflict problems. Compared with optimal control, differential game is a theory that studies the optimal strategy of two or more parties. resear...
