粗糙控制中的数据预处理

Data preprocessing in rough control

粗糙控制是一种根据观测信息数据获得控制策略的方法,其数据预处理结果对于最终生成的控制规则至关重要。本文对粗糙控制中的数据预处理方法进行探讨,提出了一些改进方法,尤其是采用优胜劣汰法去除不一致数据。将这些方法用于弓长岭阳离子反浮选粗糙控制模型的数据预处理过程,取得了较好的效果。

Rough control is such a method that acquires control rules according to the data observed. The results of data preproeessing in rough eontrol, therefore, is vital to the final produeed eontrol rules. Methods applied in data preproeessing are diseussed in this paper. At the same time, some improvements of these methods are proposed, and espeeially a new algorithm to get rid of the ineonsistent data is put forward. These methods have been applied in the rough eontrol of eation anti-floatation in Gongchangling , receiving remarkable effect.
