无人战机近距空战微分对策建模研究

Research on Close Air Combat Modeling of Differential Games for Unmanned Combat Air Vehicles

针对无人战机(UCAV)在空战格斗中的自主决策问题,在UCAV的六自由度模型的基础上,将微分对策与机器博弈相结合;通过引入机器博弈中的"变值"思想,改进了传统的以"角度优势"作为支付函数的微分对策模型。当UCAV处于不同的空战态势时,该模型体现了同样的角度变化所获得的收益不同的真实状况,使UCAV的空战策略能够更趋智能与合理,仿真结果验证了算法的合理性与有效性。

Based on a six-degree-of-freedom model of unmanned combat air vehicles(UCAVs),a differential countermeasure was combined with computer game for the problem of autonomous decision of UCAVs in air combat.The traditional differential game model which uses 'angle advantage' as payoff function was improved by introducing 'changing value' in the computer game for reference.When UCAV is in different air combat situation,the model embodies the real air combat situation of that the different incomes are obtained with the change of the same angle,so it makes the air combat strategies more intelligent and more reasonable.The simulation results show that the algorithm is rational and effective.
