Abstract
According to Kalman filter and multiple-failure-hypothesis based testing, the sensor failures are detected, isolated and accommodated in turbofan engine control system. Principles and algorithms of sensor failure detection, isolation and accommodation are given. Sensor failure diagnosis process for some typical sensor failures is simulated. Simulation results illustrate that this method can immediately and effectively detect, isolate and accommodate sensor failures, no mistake and failure reports were found.
