A New Paradigm of Fault Diagnosis for Dynamic Systems
摘要
The short re-visit of the observer-based fault detection technique and the state of the art review in the previous chapter disclose that there exist a number of open and challenging issues even after extensive studies over past decades. These include: efficient and optimal detection of parametric (multiplicative) faults, in particular in the presence of model uncertainties as well as in feedback control systems, definition and introduction of convincing and mathematically established metrics to measure the distance between nominal and faulty operations for fault detection purpose or the distance between two different classes of faults towards fault isolation.
