Distributed Fault-Tolerant Control of Large-Scale Systems: An Active Fault Diagnosis Approach

Fault-Tolerant Replication Management in Large-Scale Distributed Storage Systems

Failures of all forms happen: from losing single network packets to site-wide disasters. Since businesses rely heavily on their data, it is imperative that failures require minimal time and effort to repair and that the service interruption during the failure or repair period should be as short as possible. To this end, the ideal system should repair itself, relying on humans only when absolute...

Design of Distributed Fault Tolerant Control Systems

When dealing with large-scale complex networked control systems, designing FDI/FTC systems is a very difficult task due to the large number of sensors and actuators spatially distributed and networked connected. Despite the research effort on developing FTC systems for NCS most of these developments still being designed globally leading to centralized FTC solutions inadequate to NCS or, assume ...

Fault-tolerant Distributed Systems

Distributed systems have two key advantages: they increase the quality of our interaction with computers and the quantity of resources available to us. The quality increases as components of a distributed system hide failures from users and render a service more reliable (safer from loss) andmore available (less downtime). Increases in quantity, such as computational power and storage capacity,...

Fault Diagnosis and Fault-tolerant Control

An Adaptive Approach to Active Fault-Tolerant Control

In this Faults or process failures may drastically change system behaviour leading to performance degradation and instability. The reliability and fault-tolerance of a control system can be achieved through the design of either an active or passive Fault Tolerant Control (FTC) scheme. This paper proposes a new approach to fault compensation for FTC using fault estimation by which the faults act...
