基于原理模型的导弹故障诊断系统设计

Design of Missile Fault Diagnosis System based on Principle Model

为解决传统诊断系统知识获取难、移植性差的问题,提出了基于原理模型的复杂系统故障诊断方法;以导弹武器系统结构与行为分析为基础,应用数字逻辑推演方法,建立系统等效仿真模型,利用期望值与观测值之间的冲突迅速确定最优搜索路径方法,研究高效的系统仿真与推理算法,实现了导弹武器系统故障的快速自动诊断。

To resolving problems of knowledge acquisition and less portability of traditional diagnosis system, it propounds complex sys tern fault diagnosis method based on principle model. Based on the analysis of missile weapon system＇s structure and action, by applying digit al logic deduce method, builds up the system equivalent simulate model, then by searching path orienting method from conflict between ex pectation and observation, it studies efficient system simulate and deduce method, and implements automatic missile weapon system fault diagnosis.
