Abstract: The fuzzy dynamic observer diagnosis method is proposed for the T-S fuzzy system with unknown inputs and multiple faults. The emulation result shows that the method is exact and valid for decoupling of the multiple faults like simpler reasoning.

Key words: fuzzy reasoning, fuzzy recognition, fuzzy dynamic observer, fault diagnosis
