Abstract EN
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.
The accommodation scheme is based on the generalized internal model control architecture recently proposed for fault-tolerant control.
In order to improve the performance after a fault, the compensation is considered in two steps according with a fault detection and isolation algorithm.
After a fault scenario is detected, a general fault compensator is activated.
Finally, once the fault is isolated, a specific compensator is introduced.
In this setup, multiple faults could be treated simultaneously since their effect is additive.
Design strategies for a nominal condition and under model uncertainty are presented in the paper.
In addition, performance indices are also introduced to evaluate the resulting fault-tolerant scheme for detection, isolation, and accommodation.
Hard thresholds are suggested for detection and isolation purposes, meanwhile, adaptive ones are considered under model uncertainty to reduce the conservativeness.
A complete simulation evaluation is carried out for a DC motor setup.
