Abstract
In this contribution a fault accommodation strategy is suggested for LTI systems. The faults and perturbations are considered as additive signals that modify the output measurement. The accommodation scheme is based on the generalized internal model control architecture recently proposed [17] 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 simultaneously treated since their effect is assumed to be additive.
