双重控制导弹微分对策制导方法

摘要

针对单一鸭舵控制或尾舵控制的不足,基于双边优化微分对策理论给出了一种双重控制微分对策制导律,实现了二者的有效融合.对该制导律微分对策空间进行了分析,分别研究了理想拦截情形和非理想拦截情形下鞍点解存在的条件.考虑量测噪声因素,进行了估计器和目标拦截性能指标的设计,并基于蒙特卡罗法进行了仿真.结果表明相比于单一的鸭舵或尾舵控制,该双重控制制导律具有较好的目标拦截性能和较高的单发命中概率.%According to the disadvantages of single canard fin control or tail fin control, a novel dual control differential game guidance law is presented based on two-sided optimization game theory to realize the fusion of these two control methods. The differential game space of this guidance law is analyzed and the existence conditions of saddle point solutions for perfect interception scenario and non-perfect interception scenario are researched. With the consideration of noisy measurements, an estimator and a performance index are designed.Based on Monte Carlo simulation, the results show that this dual control guidance law has better target interception performance and higher single shot kill probability as compared with the single control scenarios.
