An intelligent hierarchical approach to actuator fault diagnosis and accommodation
TL;DR: In this article, an intelligent hierarchical approach to automatically detecting, isolating, and accommodating faults in flight control systems is presented, where a new nonlinear fault diagnosis scheme is used to detect the occurrence of any faults and to determine the particular component that has failed.

Analytical redundancy and the design of robust failure detection systems
E. Chow,Alan S. Willsky +1 more
TL;DR: In this article, a robust failure detection and identification (FDI) process is viewed as consisting of two stages: residual generation and decision making, and it is argued that a robust FDI system can be achieved by designing a robust residual generation process.
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.
