Abstract: A gas turbine engine inlet sensor fault detection and accommodation system comprises an engine model, an engine parameter comparison block, an inlet condition estimator, control laws, and a fault detection and accommodation system. The engine model produces a real-time model-based estimate of engine parameters. The engine parameter comparison block produces residuals indicating the difference between the real-time model-based estimate of engine parameters and sensed values of the engine parameters. The inlet condition estimator iteratively adjusts an estimate of inlet conditions based on the residuals. The control laws produce engine control parameters for control of gas turbine engine actuators based on the inlet conditions. The fault detection and accommodation system detects faults in inlet condition sensors, selects sensed inlet conditions for use by the control laws in the event of no fault, and selects estimated inlet conditions for use by the control laws in the event of inlet condition sensor fault.
