Simultaneous control and fault detection for discrete-time switched delay systems under the improved persistent dwell time switching
TL;DR: In this paper, a more general switching law is designed, where the resulting PDT is dependent on the state delay, and the time-varying output-feedback-based controller/residual generators are provided such that the closed-loop system is with the non-weighted H _ index for fault and l 2-gain for disturbance.

Model-free actuator fault detection using a spectral estimation approach: the case of the DAMADICS benchmark problem
Fabio Previdi,Thomas Parisini +1 more
TL;DR: In this paper, the authors present the application to the DAMADICS benchmark fault detection problem of a model-free fault detection technique based on the use of a specific spectral analysis tool, namely, the Squared Coherency Functions (SCFs), which is sensitive to the occurrence of significative changes in the plant dynamics.

Automated Fault Diagnosis and Accommodation Control for Mechanical Systems
TL;DR: A fault diagnosis and accommodation control scheme is designed, which is applicable to mechanical systems and developed by designing a nonlinear observer to detect faults and trigger fault accommodation control to compensate the effects of the fault function.
