故障检测中阈值的一种自适应选择方法

An Adaptive Threshold Selection Method in the Fault Detection

在故障检测中 ,合理的阈值选择对残差的评定有至关重要的影响。本文首先归纳总结了这方面的研究成果 ;然后 ,基于RMI(ReachableMeasurementIntervals)方法 ,给出了在闭环条件下的一种自适应阈值选择方法 ;并通过计算机仿真验证了这一方法的有效性。

The proper threshold plays an important role in the fault detection. This paper first summarizes the state of the art in this field, then puts forward an adaptive threshold selection method in closed loop dynamic systems on the basis of RMI (Reachable Measurement Intervals). And computer simulation results demonstrate the effectiveness of the proposed approach.
