Abstract :
We provide a robust fault estimation and isolation scheme for periodic systems. The observer is designed using an H2 estimation approach with the fault considered as an input to the system. The model used for residual generation provides robustness with respect to disturbance inputs. Two illustrative examples, including computer simulation of periodic systems, are provided.
