| Abstract: | In order to diagnose the control rudder damaging fault,the overall filter algorithm was used to detect fault,and then faulty information was extracted by parity space algorithm.Taking dual hypothesis detection as the judgment criteria,sensor data fusion was adopted for the early warning,verification and isolation.Simulation results have indicated that the method can greatly enhance the speed and precision of fault diagnosis. |
