| 摘 要： | 发射决策系统是在测试发射段对运载火箭进行故障诊断的专家系统,发射决策系统的推理技术需要适应运载火箭测试项目繁多,测试数据量庞大、更新快速,可供诊断的时间有限等特点.快速推理技术分为事实匹配和规则匹配2个环节,借鉴Rete匹配算法的设计思想,提出了事实匹配网络结构,提出规则和黑板的向量表示方法,定义向量与运算实现规则匹配,构建规则匹配网络完成规则匹配.在某型号运载火箭发射决策系统中的应用结果表明,快速推理法推理速度快,推理结果准确,程序实现占用系统资源少,满足实时性要求.

| Abstract: | The launching decision-making system is an expert system which can diagnose the faults of the launch vehicle during the pre-launch testing and give the auxiliary repair strategy and launch decision.In order to achieve the quick fault diagnosis,the launching decision-making expert system should use a fast inference algorithm because there are massive test data need to be processed and the time for diagnosis is quite short.Therefore,a fast inference algorithm including the fact-matching and rule-matching was ... |
