The Improved Adaptive Filter Algorithm Applied to Sensor of Control System for Failure Detection and Identification

Using standard multiple model adaptive filter to detect faults,a bank of Kalman filters are needed to finish filtering computation.When a large number of kalman filters are used,MMAE can be a very costly algorithm.An improved filter algorithm for MMAE is developed that uses a single Kalman filter to produce equivalent residuals of a complete Kalman filter bank.The computation cost of the method is less than the stand Kalman filter bank algorithm.
