Robust FDI applied to thruster faults of a satellite system
TL;DR: In this article, the authors proposed a robust estimation approach to the problem of the design of residual generators in order to realize complete diagnosis schemes when realistic faults are present on the simulated system.

Sliding mode observer based incipient sensor fault detection with application to high-speed railway traction device.
TL;DR: Three levels of novel adaptive thresholds are proposed based on the reduced order sliding mode dynamics, which effectively improve incipient sensor faults detectability and case study of on the traction system in China Railway High-speed is presented.

LPV Model-Based Tracking Control and Robust Sensor Fault Diagnosis for a Quadrotor UAV
Francisco-Ronay López-Estrada,Jean-Christophe Ponsart,Didier Theilliol,Youmin Zhang,Carlos-Manuel Astorga-Zaragoza +4 more
TL;DR: A quadrotor modelled as a Linear Parameter Varying (LPV) system is considered as a target to design and to illustrate the proposed methodologies, and a robust LPV observer is designed in order to perform fault detection and isolation.

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.
