摘要
提出了一种针对决策信息系统的属性约简方法,并将其应用到异步电机速度模型结构辨识上.同时,讨论了去除离散化数据中不一致规则的方法.结果表明,约简之后的速度模型结构与实际调速系统中影响电机转速的因素相符合,从而表明该算法是有效的.
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 con-forms to the impact factor of actual motor speed, which indicates that the method is effective.
