The paper presents a drift sensor fault detection scheme for a class of nonlinear uncertain system with partially measurable state variables. A rigorous fault detectability and detection-time interval analysis is illustrated. Moreover, the set of detectable sensor faults is characterized using off-line information and an upper bound on the fault detection interval is derived. Finally, a monotonicity property of the detection-time interval upper bound with respect to the magnitude of sensor faults is presented.

Abstract
The paper presents a drift sensor fault detection scheme for a class of nonlinear uncertain system with partially measurable state variables. A rigorous fault detectability and detection-time interval analysis is illustrated. Moreover, the set of detectable sensor faults is characterized using off-line information and an upper bound on the fault detection interval is derived. Finally, a monotonicity property of the detection-time interval upper bound with respect to the magnitude of sensor faults is presented.File in questo prodotto:
