Application of One-Step Prediction Influence Diagram in Air Combat Maneuvering Decision

A multistage influence diagram game based on one-step prediction is put forward for modeling the maneuvering decisions of UCAV in air combat.In modeling the decision system,the elements that have effect on UCAV maneuvering decision are taken into consideration,including the dynamical equation of UCAV,the pilots'preferences and conditions of uncertainty and so on.The UCAV optimal control sequences with respect to dynamical models are obtained by solving the influence diagram game with a one-step prediction control approach.In this approach,the time horizon of the original game is truncated,and a feedback Nash equilibrium of the dynamic game is determined and implemented at each decision stage.To demonstrate the validity of the influence diagram game,particle motion equation was used in UCAV modeling,and VC++ was used to implement the maneuvering decision.Analysis showed that the method presented here offers a new UCAV maneuvering decision algorithm,and enhances UCAV autonomous decision-making system.
