摘要
火控系统的精度是一个非常重要的战术技术指标,而惯导系统的可靠性则对保证火控系统的精度起着重要的作用,冗余技术是提高惯导系统可靠性的有力保证。以陀螺仪为例建立了惯性导航设备冗余度优化设计的马氏决策控制模型,并进行了验证分析,证明对此模型应用策略迭代算法的科学性与合理性。仿真结果表明,所建立的模型能够反映惯性导航设备冗余度优化设计的实质,仿真结果能够为SINS(捷联惯性导航系统)冗余结构性设计提供一定的工程参考。
Precision of fire-control system is a very important index of tactics and technique, but reliability of inertial navigation system is very important to ensure precision of fire-control system, while redundancy technique is powerful ensure to promote.Model for Markov decision process of optimization of redundancy degree of inertial navigation unit( INU) is established and verified through simulation by MATLAB, and it is presented that using policy iteration algorithm is practical and rational. Simulation results show that the above established model will be competent for design target, and materials presented in this paper have engineering value for design of redundant inertial navigation unit.
