The aim of model-based diagnosis is to find faulty components in the model from observations. Set-covering is an approach to diagnosis when the causal relations between symptoms and disorders are clearly defined. The new method combines the model-based approach and set-covering approach. The ...
Model-based diagnosis refers to reasoning from first principles that declaratively describe a system's structural and behavioral properties. In recent years, model-based diagnosis has proven successful in such areas as software design and fault localization in hardware. However, although the basic princ...
In this paper, the focus is on model-based diagnosis (MBD), which formalizes reasoning from first principles. The contribution of the paper is twofold. On the one hand, the standard MBD representation framework is enriched to permit default information. On the other hand, we exploit the ...
An alternative approach, model-based diagnosis, utilizes a model of the system and compares its predicted behavior against the actual behavior of the system for diagnosis. This paper presents a novel technique based on probabilistic models. Therefore, it is natural to include uncertainty in the ...

Two kinds of model-based diagnosis (MBD) are combined to achieve high diagnosis efficiency and recognition ability of fault types. The model library and diagnosis engine are the two main parts of the diagnosis system, both of which have the two-level structure that contains a consistency-based ...
This paper introduces a hidden Markov model (HMM)-based fault diagnosis technique for DC-DC boost converter. Four HMMs are trained to model parameter variations in the power converters. Each HMM is created based on 14 visible states, which generates probability of each time step matching a signa...

In this paper, the design of a nonlinear observer-based fault diagnosis approach for polymer electrolyte membrane (PEM) fuel cell air-feed systems is presented, taking into account a fault scenario of sudden air leak in the air supply manifold. Based on a simplified nonlinear model proposed in...
A large amount of knowledge on model-based fault diagnosis has been ac cumulated through the literature since the beginning of the 1970s. However, publications are scattered over many papers and a few edited books. Up to the end of 1997, there is no any book which presents the subject...
