摘　　要：随着现代战争模式向全域化、智能化、精准化不断发展,引信作为弹药的“大脑”越来越成为决定战争胜负的关键,而传统的线性开环控制的引信设计方法已经不能满足新一代灵巧引信的需求.本文基于环境-目标的非线性耦合干扰对时延的影响机理,提出了虚拟闭环和抗时延信息融合两大设计思路,进一步完善了三元级联控制设计架构.通过两个具体实例,即多层硬目标侵彻引信和高速交会近炸引信两种典型武器系统中的应用实例,验证了所设计控制架构的性能优越性.仿真和实验结果表明,本文所提出的三元级联控制方法相比于传统的引信控制方法能够有效提升探测识别能力、起爆控制精度和弹药毁伤效能,有望成为未来灵巧引信向智能引信发展的理论基础.With the continuous development of the modern war mode to the universal, intelligent, and precise mode, the fuze, as the “brain” ofammunition, has increasingly become the key to determining the outcome of a war. However, the traditional linear open-loop controlfuze design method has been unable to meet the needs of the new generation of smart fuzes. In this paper, based on the influencemechanism of the nonlinear coupling interference of the environment target on the fuze, two design ideas of virtual closed-loop andanti-delay information fusion are proposed, and the design architecture of the “three-element” cascade control is further improved.Furthermore, the performance superiority of the designed control architecture is verified through the examples of two typical weaponsystems, namely, the multi-layer hard target penetration fuze and high-speed encounter fuze. The simulation and experimental resultsshow that compared with the traditional fuze control method, the “three-element” cascade control method proposed in this paper caneffectively improve the detection and identification ability, initiation control accuracy, and ammunition damage efficiency of aweapon. Therefore, this study is expected to become the theoretical basis for the future development of smart fuzes.
