Abstract :
A method for detecting sensor faults in a turbofan engine is presented. The proposed method consists of an observer with integral action and an adaptive detection threshold. The threshold is computed with the assumption of parametric uncertainty in the process model. Successful simulations with sensor data from an RM12 jet engine shows that the method is capable of detecting even a very small increase in sensor noise promptly without generating false alarms.
