A Fault Diagnosis of Dynamic Systems Based on Unknown Input Observer Schemes
介绍了动态系统故障诊断的未知输入观测器组方法的原理和设计步骤。对于线性离散定常系统，详细推导了基于矩阵束的克罗内克尔标准形变换的观测器设计算法，所得观测器对于指定故障敏感，对其他未知输入解耦。重复该设计过程，可得到观测器组，实现鲁棒的动态系统故障检测和分离。最后讨论了设计方法的有关问题。
The principle and design procedure of unknown input observer schemes for fault diagnosis of dynamic systems are described in this paper. For discrete linear time invariant systems, detailed deduction is given to the algorithm of observer design based on the Kronecker canonical form transformation of matrix pencil. The resulted observer is sensitive to specific faults and is uncoupled from other unknown inputs. Recursively using the above procedure gives a sc…查看全部>>
