Study on the Condition of Separable Fault of Serial Nonlinear System Under the Process Noise

Abstract:

Through the detailed derivation, this paper proves that the separability is objective existence and gives the form unity conclusion in the condition of the faultseparation about serial linear system and serial nonlinear system when exist the process noise. This paper also combines the wheels bearing fault of 552732QT electric locomotive, Shao guan 8 electric locomotives, the locomotive SS4G0446 of the concrete practice of the fault isolation.
