对全捷联微小型弹药制导问题做了系统性分析,提出了两级助推分段制导方案;研究了微小型弹药动力学模型,结合微小型弹药的特点建立了其纵向通道模型;分析了全捷联体制下制导信息获取问题,应用角速率解耦方法获取制导信息;结合动力学模型和制导信息编写了仿真程序,应用程序制导与比例导引制导设计了制导方案,完成了全捷联微小型弹药的制导设计。通过数值仿真验证了分段制导方案的可行性,为微小型制导弹药设计提供了理论基础。
A new guidance scheme is presented in this paper based on the requirement of battlefield to analyze the deeply strapdown miniature ammunition guidance system. According to the dynamics of miniature ammunition, a longitudinal channel model combining with its characteristics is set up. The critical problem of how to obtain guidance information for deeply strapdown guidance system is analyzed firstly. Then anangular rate decoupling approach is proposed in details. A program is built based on the dynamics and guidance information. A segmented guidance scheme that combines program guidance and proportional one is designed to complete the guidance of strapdown miniature ammunition. The feasibility of the segmented guidance scheme is verified by trajectory simulation, which provides a theoretical basis to the guidance design of the miniature ammunition.
