The Study of Processing to Outlier in Measured Data Based on Robust Filtering

WEN Jiangtao 1, WANG Yutian 1, SUN Jiedi 2 1.Institute of Electr. Eng. Yanshan University, Qinhuangdao Hebei 066004, P.R.China 2.Institute of Information Sci. and Eng. Yanshan University, Qinhuangdao Hebei 066004 P.R.China  
Based on M Estimate technology of robust filtering, this paper proposes an entirely new method for the processing to the outlier, which exist in the surface parameter measurement of large rotary machine. It also presents the mathematic model and result of experiment. After the processing using this method, the data avoid to be parted in timely sequence, and the effect of the outliers in the data is eliminated. This process outcome is satisfied and well prepares for the further processing, storing and displaying of the data.
