Faults and errors are an unavoidable aspect of high performance computing systems. Emerging exascale systems will contain billions of hardware components and complex software stacks. In addition, higher fabrication density and power challenges will further compound fault detection, management and recovery. Efficient fault tolerance and resiliency frameworks are thus of immense importance in the...

Modern manufacturing facilities are large scale, highly complex, and operate with large number of variables under closed loop control. Early and accurate fault detection and diagnosis for these plants can minimise down time, increase the safety of plant operations, and reduce manufacturing costs. Fault detection and isolation is more complex particularly in the case of the faulty analog control...

The paper presents a model-based design method for fault diagnosis (detection and isolation) and fault-tolerant control (FDI/FTC).The design is based on pole placement of input-output models. Furthermore, the design of an output feedback controller is divided into two independent design tasks: a generalized state and fault observer design and a fault feedforward and state feedback design.

This article discusses results of an investigation into requirements for and problematic aspects of implementing a decision theoretic data-centric approach to the problem of data driven fault detection and diagnosis for aircraft and their subsystem, suitable for offline application to Flight Operational Quality Assurance (FOQA) type data. We discuss fundamental considerations for this type of a...
