A recently developed maximum likelihood failure detection algorithm, based on processing the residuals from an observer designed on the assumption of no failures, is applied to the problem of detecting and correcting gyro or accelerometer failures in the vertical axis of an aircraft flight control system. Design calculations are illustrated with a simplified dynamic model and the effectiveness of the failure detection method is demonstrated by simulation.
