This paper introduced the good characteristic of morphological filter and its application in purification of rotor center’s orbit. Using the combination of morphological open-closing and close-opening operations, the local characteristic of the original signal could be kept and noise interferences could be eliminated effectively, then the rotor center’s orbit could be purified successfully. There is no need to consider signal’s spectrum characteristic when using the morphological filter to de-noise the corrupted signal. To verify the effectiveness of the morphological filter, the median filter was employed to process a simulated signal. The results by the morphological filter were more stationary and smoother than those obtained by other methods. And it is also more practicable and easier for on-site application.
