摘要: 针对多故障源系统的故障诊断问题,提出一种采用分散化预测滤波与两种不同类型残差相结合的诊断方法。该方法针对不同类型故障敏感的特点,利用不同类型残差,区分系统组件/执行机构故障和传感器故障;利用模型误差估计与故障各分量的对应关系,辨识和隔离系统组件/执行机构故障;利用分散化滤渡的结构,识别和隔离不同传感器故障。以卫星姿态估计系统为例,仿真验证该故障诊断方法,结果表明,分散化预测滤波与集中预测滤波相比,对多类型故障进行检测、识别以及系统重构的能力更强。

Abstract: A new fault diagnosis method for a complex system with more than one type of faults is proposed in this paperTo distinguish different faultstwo kinds of residuals generated from only one decentralized predictive filter are usedbecause they have different sensitivities to component/actuator faults and sensor faultsEven morefor a component or actuator faultthe source of it can be found exactly depending on the relationship between residuals and faultsAnd for a sensor faultit can be detected and isolated easily by using the decentralized structure of predictive filtersTo elaborate this methoda simulation for a satellite attitude determination system is presentedThe simulation results demonstrate that the decentralized structure of predictive filters is more powerful than the centralized one in fault diagnosis and system reconfiguration
