Analytical redundancy for systems with unknown inputs. Application to faults detection
Résumé
A well known method for residual or redundancy generation is extended to systems with unknown inputs. It is based on the singular form of the system equations which allows the generation of the substate of the system which is insensitive to the unknown inputs. This generation is achieved by a two-steps algorithm including, first, the elimination of the unknown inputs and second, the generation of the redundancy equations. Using these results for fault detection and isolation, we present a simulated example to illustrate our method.
