Real-time fault diagnostics

IEEE Expert, 1991
The intelligent process control system (IPCS), an integrated environment for developing complex process control and automation systems is discussed, focusing on its real-time fault diagnostics capability. IPCS has been used to build a supervisory monitoring and diagnostics system for a cogenerator plant.

Fault diagnostics and fault tolerant control

IEEE Transactions on Aerospace and Electronic Systems, 1998
A novel simultaneous fault detection and diagnostics (FDD) and fault tolerant control (FTC) strategy for nonlinear stochastic systems in closed loops based on a continuous stirred tank reactor (CSTR) is presented. The purpose of control is to track the reactant concentration setpoint.

A diagnostic fault simulator for fast diagnosis of bridge faults

Proceedings Twelfth International Conference on VLSI Design. (Cat. No.PR00013), 1999
A new diagnostic fault simulator is described that diagnoses both feedback and non-feedback bridge faults while using information from fault simulation of single stuck-at faults. A realistic fault model is used which considers the existence of the Byzantine Generals Problem. The approach has been demonstrated for two-line bridge faults on several large

Diagnostic Test Generation for Arbitrary Faults

2006 IEEE International Test Conference, 2006
It is now generally accepted that the stuck-at fault model is no longer sufficient for many manufacturing test activities. Consequently, diagnostic test pattern generation based solely on distinguishing stuck-at faults is unlikely to achieve the resolution required for emerging fault types.

Fault isolation in an integrated diagnostic environment

IEEE Design & Test of Computers, 1993
The use of information flow models to conduct efficient fault isolation strategies is described. Of particular concern is optimizing diagnosis to minimize some objective cost function. A technique that can include multiple cost criteria such as test time, skill level, and failure frequency, as well as information value, is discussed. >

Gaining diagnostic information for fault isolation

2013 IEEE International Conference on Information and Automation (ICIA), 2013
Robots in dynamic and uncertain environments are vulnerable to mission failures due to external perturbation or internal malfunctions. Diagnosis is the process to detect, locate or even assess the fault. Since robots rely on their function modules to sense the external environment, it is difficult to locate the fault under uncertainties of robot ...

Diagnostic Fault Simulation of Sequential Circuits

Proceedings International Test Conference 1992, 2005
In this work we describe a diagnostic fault simulator for sequential circuits which evaluates the effectiveness of a given test set in distinguishing between faults. Diagnostic fault simulation is performed on several ISCAS89 sequential benchmark circuits using two diferent deterministic test sets for each circuit.

Characterization of probabilistic faults diagnostic models

2006 International Conference on Information Technology: Research and Education, 2006
This paper suggests a characterization of probability-based search models describing various fault diagnostics processes, which are widely used in the current practice of complex computer systems and networks systems maintenance and service. The characterization is performed in terms of some tuples including: characteristics of fault models ...

A novel approach to fault diagnostics and prognostics

2003 IEEE International Conference on Robotics and Automation (Cat. No.03CH37422), 2004
A novel fault diagnostics and prognostics algorithm based on hidden Markov model (HMM) is proposed. The algorithm combines fault diagnostics and prognostics in a unified framework. The algorithm has been fully tested by using experimental data from a rotating shift testbed in our laboratory.

Experiences with concurrent fault simulation of diagnostic programs

International Test Conference 1988 Proceeding@m_New Frontiers in Testing, 1990
A methodology is presented for fault-simulation of system level diagnostic programs involving large models (50000 to 200000 gates) and long test sequences. Accuracy of memory models, interplay of target faults with diagnostic program development, and creation of shorter diagnostics are topics covered.
