Reliability is naturally a subjective concern in tile analysis and design of fault-toleranl control systems. Reliability is rarely regarded as an objective crite- rion that guides a control system design in an inte- grated manner. The reliability analysis of fault-tolerant control systems is performed using Markov models.

Reliability properties peculiar to fault-tolerant control systems are emphasized. As a consequence, coverage of failures through redundancy management can be severely limited. Dugan J.B., Lyu M.R. () System-Level Reliability and Sensitivity Analyses for Three Fault-Tolerant System Architectures.

In addition, the system includes a scheme to detect failures in individual actuators and, as a. INTRODUCTION New control techniques and design approaches have been developed to treat system component faults and to improve system reliability and availability, which are collectively called Fault Tolerant Control Systems (FTCS's).Cited by: 1.

The estimated system reliability is consequently strongly dependent on the model itself. Because the behavior of a fault-tolerant, highly reliable system is complex, formulating models that accurately represent that behavior can be a difficult task.

Mathematical models of fault-tolerant systems must cap-Cited by: Reliability modeling of fault tolerant control systems long-term system reliability behavior during an off-line analysis.

As a function criterion, R(t) is not often used as an objective or a constraint in the design phase. An al-ternative scalar reliability index, Mean Time To Failure (MTTF), is usually preferable for a controller or a system.

In this paper the integration of reliability evaluation in reconfigurability analysis of a fault-tolerant control system is con-sidered. The aim of this work is to contribute to reliable fault-tolerant control design. The admissibility of control recon-figurability is analyzed with respect to reliability.

In order to meet high reliability requirement of safety-critical processes, major progress has been made in fault tolerant control systems (FTCSs).

FTCSs usually employ fault detection and isolation (FDI) schemes and reconfigurable controllers to accommodate fault effects, also Cited by: 5.

In this book, bestselling author Martin Shooman draws on his expertise in reliability engineering and software engineering to provide a complete and authoritative look at fault tolerant computing. He clearly explains all fundamentals, including how to use redundant elements in system design to ensure the reliability of computer systems and by: IV.

Brief history of common cause failure analysis Reliability analysis was developed to understand the frequent vacuum tube failures in electronic systems before the transistor was invented. Fault tree analysis was developed in the early ’s by Bell labs and Boeing to analyze missile systems and later commercial aircraft.

The objective is to maximise the reliability of the fault tolerant software satisfying a budget constraint and a constraint on the mean execution time of the software.

This analysis proves that the control reconfigurability is a system property. procedures. Such software is oriented on the reliability analysis of series and parallel systems.

Optionally, that software can also be used for computing the reliability of fault tolerant systems with complex reliability behavior, for example, a flight computer with implementation of majority-voting system 2-out-of-3 microprocessorsAuthor: Yuriy Pashchuk, Yuriy Salnyk, Serhiy Volochiy. Key-Words: fault tolerant, reliability, dependability, control, microprocessor system, separate channel 1 Introduction It is a well known fact, that through multiple redundancy and iterative redundancy addition, it is possible to build a system with arbitrarily high preliminary defined reliability [1].
