Abstract:
A method of detecting and/or isolating a fault of a sensor in a system in substantially real time or in non-real time (e.g., using off-line analysis). A spectral energy of a signal of the sensor is determined over a predetermined range of frequencies within a window of samples of the signal. The determined spectral energy is evaluated for consistency with a substantially current state of the system.
