Sensor placement of flywheel under diagnostic criteria and cost estimation

  • 摘要: 以动量轮为例开展诊断测点配置与成本评价方法研究.分析系统功能模块输出与故障模式之间的关系,建立DG图故障传播定性模型.对DG图回路进行处理,生成满足可检测性和可分离性的根节点,建立偶图.采用改进的贪婪算法选取关键测点,给出诊断测点配置方案.考虑测点对系统体积、重量、功耗、处理能力等资源的要求,提出用资源占用度的概念表示成本计算模型,合理设计了资源占用度的表达形式,可以突出某项重要资源要求对评价结构的影响,也可以避免某些重要指标被弱化,并且在需要考虑其他资源要求时可扩展.通过成本模型对测点配置方案进行评价.
