Fault diagnostics and fault tolerant control
IEEE Transactions on Aerospace and Electronic Systems, 1998A 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.

Integrated intelligent fault diagnostics
Proceedings of IEEE National Telesystems Conference - NTC '94, 2002Since the 1970s, awareness, interest, and emphasis in the testability discipline have been increasing. This discipline is an extension of system design, reliability assessment, and test engineering and is an increasingly important part of Integrated Product Development (IPD) teams.

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.

Internal Combustion Engines Fault Diagnostics
2020This article describes the methods of diagnosing internal combustion engines (ICE). The conclusion is drawn that the majority of modern methods and ICE diagnostic devices don’t solve fully a problem of determination of technical condition of the engine, often are labor-consuming and expensive. The choice of a method and mode of diagnosing of ICE on the

Fault Diagnostics of Rotating Machinery
2011 21st International Conference on Systems Engineering, 2011This research extends the concept of [Lehrasab, 1999] to the domain of rotating machines. It aims at developing novel fault diagnostics techniques for the motor or rotating machines for diagnostics that is costeffective and easier to deploy from industrial perspective.

Gear Diagnostics – Fault Type Characteristics
Annual Conference of the PHM Society, 2014To date, the majority of existing Condition Indicators for gears are based on various statistical moments of a recorded time history. A supplementary analysis proposed in this study, shall suggest an approach that may, in the future, enable the identification of faulty gearwheel and possibly fault type in the system.

A Fault Diagnostic Algorithm for Fault Tolerant Control Systems
IFAC Proceedings Volumes, 1986Abstract A new fault diagnostic algorithm for locating a fault and estimating its magnitude in control systems is proposed for use in the fault tolerant control system. The proposed algorithm is found to be highly effective for control systems with multiple PID controllers, which is demonstrated by a simulation experiment.

Knowledge-Based Fault Diagnostic System Using Binary Fault Tree
Applied Mechanics and Materials, 2013For the improvement of reliability, safety and efficiency advanced methods of fault diagnosis, new technology and method such as expert system become increasingly important for many kinds of fault diagnosis. Thereby, the classification principle of system structure is used to build the hierarchical analysis model of combustion engine.

Fault Simulation of Diagnostic Programs
1994This chapter is an evolution of recent work [1] on fault grading, the detection and isolation of faults, and concurrent simulation of the good and faulty versions of a diagnostic program. Many program versions are executed (simulated) concurrently, progressing synchronously through the dimension of time. Various problems exist, such as the detection of

A diagnostic fault simulator for fast diagnosis of bridge faults
Proceedings Twelfth International Conference on VLSI Design. (Cat. No.PR00013), 1999A 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
