A system is fault-tolerant if it maintains some form of correctness in the presence of faults. Fault-tolerant systems are necessary in many application areas of computing, especially where the failure of a computer system may lead to considerable damage. However, the development of fault-tolerant systems is a difficult task and requires rigorous and scientifically sound engineering methodologie...

Synchronization is used in dual redundant fault-tolerant system to make two computers work jointly. It determines the work mode and controls the operations of the system. The paper presents a dual redundant fault-tolerant system and proposes its process of synchronization based on task. The synchronization treats task as the minimal operation unit. And it is implemented with the assist of dual-...

We investigate a novel adaptive fault-tolerant control method for time-varying failure in high-speed train computer systems and propose a fault model for such systems. First, the dynamics of high-speed train systems are analyzed and a multiple point-mass model is developed. When actuator outputs deviate from the expected value, a novel adaptive fault-tolerant control method based on Lyapunov st...

a new fault tolerant controller (ftc) has been presented in this research by integrating a fault detection and diagnosis (fdd) mechanism in a nonlinear model predictive controller framework. the proposed fdd utilizes a multi-sensor data fusion (msdf) methodology to enhance its reliability and estimation accuracy. an augmented state-vector model is developed to incorporate the occurred sensor fa...

An adaptive system diagnosis fault tolerance method for distributed system. The system is comprised of a network including N nodes where N is integer and greater than equal to 3 and each node is able to execute an algorithm to communicate with the network. A computer network, often simply referred to as a network, is a collection of hardware components and computers interconnected by communicat...

A small to moderate sized modern computer system employs advanced features such as fault-tolerance (see Fault-tolerant systems), resource sharing and contention, concurrency and synchronization, timeliness (see Real-time systems), and degradable performance. When such a computer system is being designed and implemented, it becomes essential to answer “what-if” questions and carry out trade-off ...

fault tolerance is one of the important issues in industries, such as transportation, military, chemical and nuclear sectors. reliability and safety are two vital attributes of fault tolerant systems, and redundancy is a common way to improve these parameters. this article studies the impact of including cold standby spares in system architecture. to do this, it uses the markov model of the sys...
