Sliding mode observers for fault detection and isolation
TL;DR: This paper considers the application of a particular sliding mode observer to the problem of fault detection and isolation using the equivalent output injection concept to explicitly reconstruct fault signals.

System health monitoring and prognostics — a review of current paradigms and practices
TL;DR: The most common maintenance and repair strategy is "fix it when it breaks" as discussed by the authors, which can provide relatively high equipment reliability, but it tends to do so at excessive cost (higher scheduled downtimes).

Disturbance Observer for Estimating Higher Order Disturbances in Time Series Expansion
TL;DR: For a class of linear systems, an output-based disturbance observer of reduce order is newly derived from the proposed full state disturbance observer, and its potential applicability will be demonstrated by an example.

Paper: A survey of design methods for failure detection in dynamic systems
TL;DR: This paper surveys a number of methods for the detection of abrupt changes in stochastic dynamical systems, focusing on the class of linear systems, but the basic concepts carry over to other classes of systems.

A survey of design methods for failure detection in dynamic systems
TL;DR: A number of methods for detecting abrupt changes (such as failures) in stochastic dynamical systems are surveyed in this paper, where tradeoffs in complexity versus performance are discussed, ranging from the design of specific failure-sensitive filters, to the use of statistical tests on filter innovations, and the development of jump process formulations.
