Double Fault Detection of Cone-Shaped Redundant IMUs Using Wavelet Transformation and EPSA
A model-free hybrid fault diagnosis technique is proposed to improve the performance of single and double fault detection and isolation. This is a model-free hybrid method which combines the extended parity space approach (EPSA) with a multi-resolution ...

Robust MPC for actuator-fault tolerance using set-based passive fault detection and active fault isolation [PDF]
In this paper, an actuator fault-tolerant control (FTC) scheme is proposed, which is based on tube-based model predictive control (MPC) and set-theoretic fault detection and isolation (FDI). As a robust MPC technique, tube-based MPC, can effectively deal

Multiple Fault Detection And Isolation
Abstract Model-based fault detection methods allow the generation of residuals as fault indicators. Isolation is generally based on the incidence matrix structure. Simultaneous faults generate a new fault signature, corresponding to the superposition of the fault effects.

Fault Detection, Isolation, and Accommodation for LTI Systems Based on GIMC Structure
In this contribution, an active fault-tolerant scheme that achieves fault detection, isolation, and accommodation is developed for LTI systems. Faults and perturbations are considered as additive signals that modify the state or output equations.
