| Abstract: | An Attribute reduction method of the decision information system is proposed,and this method is applied to the identification of the asynchronous motor speed model structure.The method of the removing inconsistency rules in the discrete data is also discussed.The result shows that the structure of speed model conforms to the impact factor of actual motor speed,which indicates that the method is effective. |
