摘　　要：对于大机动目标拦截问题,模式决策器是基于逻辑的集成估计导引系统(Integrated estimation and guidance,IEG)中的一个重要组件.为了保证系统的估计精度和制导性能,模式决策器的模式延迟应尽可能小.本文针对末制导场景,首先推导了离散时间系统零控脱靶量的估计误差模型,然后在一致性约束条件下给出了系统最大可容许模式决策延迟的数值计算方法.本文的研究结果可为IEG系统中模式决策器的设计提供指标参考.For highly maneuvering target interception, mode decision-maker is a critical component of the logicbased integrated estimation and guidance(IEG) system. To ensure the estimation accuracy and guidance performance, the mode delay of the mode decision-maker should be as small as possible. For the case of terminal guidance scenario, this paper first derives the estimation error model of the zero-effort miss distance of the discrete-time system, and then gives a numerical computing method of the maximal admissible mode decision delay under consistency constraint. The results provide an index reference for the design of(IEG) mode decision-maker in IEG systems.
