| Résumé : | The problem of fault detection and isolation (FDI) in the current sensors of a doubly-fed induction generator (DFIG) in the presence of model uncertainty is discussed in this paper. The proposed residual generator is inspired by the structure of the classical generalized observer scheme (GOS). However, each observer in this scheme is replaced by a robust H-/H ∞ fault detection filter (FDF) followed by a Kalman-like observer. The latter filters a specific frequency in the output generated by the H-/H∞ FDF. A multi-CUSUM (Cumulative Sum) algorithm is used as decision system. The approach is validated through simulations of a controlled DFIG. |
